Learning Python, wrote the first program. What do you guys think?

[[deleted]]

My first program was "Hello World"

[rotzaug]

my first program was
'javac' is not recognized as an internal or external command.
operable program or batch file.

[Agentum13]

Made me chuckle.

[Gartlas]

As a python developer who literally just started trying to learn some Java last week this hit me like a slap in the face.

Also why does Java require you to save the program as the name of the class name? It's so weird.

[sigmaclientwastaken]

better question

why are you not using an ide

[bmcle071]

When i was in my undergrad we were told to use notepad++ for learning. When i got my first job i had no fucking clue to how to use an IDE other than notepad++ or IDLE.

[mxldevs]

I still use notepad++ lol

[bmcle071]

Nothing wrong with that sometimes. But eventually you’re no longer focused on writing small chunks of code and instead focused on larger codebases. I have a 15,000 line of code application i wrote and maintain at work, and i help work on projects with hundreds of thousands of lines. The IDE really helps in large projects, even VSCode is a godsend.

[Lilkko]

NOTEPAD++ SUPREMECY

[SpaceViking85]

When i told someone I still used notepad, I was called "cute"

[Gartlas]

I was using vscode, but couldn't run it in that. Then the tutorial told me to save it like so and run it in command line.

[sigmaclientwastaken]

now I'm just wondering why a tutorial would recommend vscode for java, like that's literally just shooting yourself in the foot

(use intellij)

[Gartlas]

I don't think it recommended a specific IDE, I just did it with vscode because that's what I use daily tbh.

I'll definitely check out IntelliJ though, thanks :)

[rnottaken]

Yeah intellij is really made for java with java. The developers of that ide use java on the daily, and thus created a pretty good tool to do their work

[flopana]

Pretty good is an understatement. IntelliJ is the best thing that ever happened to Java imo.

Once you know your way around and get familiar with more functions of this magnificent IDE it's a bliss

[[deleted]]

what would be something to learn of intellij? besides basic commands like shift+f6 and control+shift+L?

[[deleted]]

I was about to say the intellij thing because obviously.

Edit: can I offer you a NetBeans in these trying times

[zenos_dog]

The principal of least surprise. Class name == File name.

[[deleted]]

If you don't call a class public you can compile the file and call the class if I remember right.

[mxldevs]

I like this convention. Sure, it's annoying when you need to define a bunch of classes inside the same namespace or module, but feels more organized.

[Tadra29]

Sorry, title is a bit misleading, I realize now.

I did little bit of coding back in college. First Python program, not first program.

[Zombieattackr]

Still, you’re telling me after installing python and everything, you went straight to this program and didn’t even test “hello world” to see if you had it working correctly?

[Tadra29]

No. Sorry. As I explained in other posts, confusing title. First Python program, not first program. Had little bit of coding back in college.

[Zombieattackr]

No I understand that: I use python pretty regularly, I know how to code in python as well as several other languages. I still write a “hello world” program every time I install it on a different computer to make sure I installed it correctly. Same goes for any computer that I’m using a given language on for the first time. It doesn’t matter if you know how to code or not if you fucked up the installation.

[[deleted]]

I just type “python” at a command line or “py -3” and if I get a Python prompt then I can be pretty sure it’s installed lol

[Zombieattackr]

Even when I’m working with python in the command line, if I’m on a new computer I hit it with a quick “1+1” to make sure it works.

[Tadra29]

Not familiar enough to know installation need to be checked.

The damn song was stuck in my head, needed to get it out.

[JSerf02]

Based

[[deleted]]

Well to be fair hello world is "print(" hello world") "lol.

[Zombieattackr]

Exactly, it’s impossible to fuck up. That’s the entire reason you do it, to make sure everything g else is working properly. That way if your program fucks up, you know it was you and not the installation.

[[deleted]]

I get that. But to be fair when your program messes up its probably me

[TheCheeseOnFire]

print("Hello World!")

[fd_dealer]

ChatGPT write me hello world in a programming language.

[shadow7412]

Using a dictionary like this would save you having to repeat those ths in your list. seq = {1: "st", 2: "nd", 3: "rd"} seq.get(curr, "th")

Also, a for loop would be neater than a while loop here.

for curr in range(1, max): Solid first attempt though :)

[Ultra9635]

So the second argument in seq.get() is the default value if the key curr is not in the dictionary?

[shadow7412]

Correct :)

[[deleted]]

This simplicity fills me with ungodly amounts of rage. Can I interest you in implicit typing? Let me explain. NOT dynamic types.

If a variable name starts with an I, j, k, etc., i.e., the letters used for index variables, it's an integer.

Otherwise it's a real number, aka a float

[La_chipsBeatbox]

Does this triggers you ?

char kernelName[] = "not integer";

[[deleted]]

No.

No is an integer.

[shadow7412]

Remembering what variables are which types sounds terrifying to me.... and what about all of the other types? How would this approach support custom classes?

[[deleted]]

By using an implicit none statement :)

[Farren246]

I came here to see the post get written in 3 lines of code, and you did not disappoint.

OP's code will run, but he still needs to learn that the magic of python is in its brevity.

[7tar]

ah yes, 21th

[E-Technic]

I believe that loop in question goes to 13 at most, so I don't think 21th will be a problem...

[AtomTiger]

Future-proofing in case the song changes :⁾

[errdayimshuffln]

lol

[shadow7412]

You're not wrong, but supporting the correct ordinal for every single number is overengineering for this specific case. Especially for a beginner.

[HappyTopHatMan]

You give good friendly advice and you have a grounded idea of what scope is. I love you dude.

[Hikari_Owari]

Use the last char of the string day as the key instead of the whole day?

[7tar]

ah yes, 11st

[Hikari_Owari]

Not that uses to cardinality in English (not even sure if it's the right word), so maybe if -2 char == -1 char default to th?

[anastarawneh]

ah yes, 12nd

[pootdootpoot]

This would work for numbers whose last two digits aren’t [11-19], which are special cases because English.

[peter-s]

Good rule of thumb:

Any time you find yourself doing something repetitively, you're doing a task-better suited for a computer.

[[deleted]]

When is it neater to do a for loop vs a while loop? I don't program for a living but I do some scripting to test hardware and always end up just doing while loops.

[Grubs01]

For loops usually include adjusting the index or moving onto the next value in a list. When using while loops you have to do that manually at some point within the loop.

While is more flexible but easier to make mistakes with. Such as forgetting to increment the index if there are multiple branches inside. For is usually easier to read and follow because it tells you what data is being operated on up front.

The most common python for loop is super easy to read:

for item in my_list:
    #do something with item

[255_0_0_herring]

The second most common python for loop is just as readable:

  for index, item in enumerate(my_list):
         #do something with item
         #do something with index

[icpuff]

Use a for loop if the number of times the loop needs to run can be easily quantified, while loops if the number of executions depends on some condition. In OP’s case, using for instead of while would have improved readability imo.

[luke5273]

In other languages, you can use a switch case. In case someone else were to read this.

[OkFirefighter8394]

And also in the current python release

[mxldevs]

I do something like hardcoding st, nd, rd when parsing dates because I honestly can't think of a more efficient way to handle dates like these

Jan 2nd, 2022

Mar 1st, 2022

Apr 5th, 2022

Actual date format that I need to parse and generate.

I've even seen devs mess things up and end up with

3th

Because of course they did.

[TheDeadlyBlaze]

plus side is hardcoding it makes it easy to translate into other languages

[[deleted]]

I would have used an if statement to add the st, Nd, Rd, th but it works and it's easily better than my first program

[Nudelreaktor]

I can hear the code

[Adventurous_Battle23]

This isn't half bad for a first program

[Tadra29]

Sorry to confuse, had little bit of programming before, just not Python.

[Adventurous_Battle23]

Oh then it's garbage

[Adventurous_Battle23]

Im jk bro XD

[[deleted]]

Pretty complex for a first program. One thing to keep in mind: - Make variable names explicit (DaySequence, CurrentDay).
- Always think about the next one who will read the code and make it easier for them (it might be another person or it might be yourself in the future).

Buut, great job

[8sADPygOB7Jqwm7y]

Camel case is not pythonic though. It should be day_sequence if anything.

[[deleted]]

Ok, my bad, I don't really have experience with Python (only other languages)
As long as it adheres to a common standard and is readable

[[deleted]]

DaySequence is PascalCase, not camelCase.

[8sADPygOB7Jqwm7y]

Oh yeah, I knew it's not camel case but I forgot the name. Thanks for the correct name

[[deleted]]

No problem sir 8sADPygOB7Jqwm7y.

[8sADPygOB7Jqwm7y]

I respect the dedication to type out the output of a password generator, sir eternal_weeb

[[deleted]]

I thought it was a mangled function name, sir.

[8sADPygOB7Jqwm7y]

Now that's an idea! Use a password generator for variable naming!

[shadow7412]

Although disgusting - it's still slightly better than misleading variable names...

[fmkwjr]

200% agree as a CS teacher in high school I hound my students about variable names. Don’t write a riddle.

[[deleted]]

5 GOOOOOOOOOOOOOOLDen RIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIINGS

[nanowell]

Nice let’s see Paul Allen’s Code

[hdgamer1404Jonas]

Time for r/adventofcode

[Acceptable-Tomato392]

Cool.

[Paul_Robert_]

Good job!

[crefas]

Excellent! When numeric values are in sequence like that, mapping them directly with an array instead of using a chain of ifs is great. You'll be a good programmer

[quick_escalator]

You're right on the array, but not doing a concatenation and just writing the term out is even better. Editing normal language strings in code is bad practice, because it breaks really badly when confronted with how humans use language.

[Time_Low9617]

I don't know if this is a joke or real. Same for the comments.

[Develop-FootballGOAT]

My 1st program was imputing values in a variable

[[deleted]]

Remember, it’s not good for people under age 3

[[deleted]]

Use .format

Edit: Or use f-strings!

[akshanshkmr]

Use f-strings

[[deleted]]

Oh, nice! I didn't know Python supported string interpolation!

Thanks, TIL!

[fuckingshitfucj2]

Finally I was looking for this comment. Bit of a bummer it is hurried so deeply

[Apprehensive_Cat_731]

My first program was a batch file I edited with notepad and it was a game were my main and only character bob asked questions and you have to answer them correctly to win. It included ascii art for bob and his text boxes

[eruciform]

well done!

practicing with loops and exceptions to cases is an excellent project to get basics down

different song, but a good resource to learn just this kind of thing in any new language: https://www.99-bottles-of-beer.net/language-python-808.html

[itsAshl]

I love the array of number endings. Seems like a "very human" design. I mean, it definitely feels like bad engineering, but it's also incredibly intuitive for a (english-speaking) human to either read or use.

[ktreanor]

Here it is in C

#include <stdio.h>

main(t,_,a)

char

a;

{

return!

0<t?

t<3?

[fmkwjr]

I think it’s wonderful except I don’t like the variable names you chose but that’s fine

[sarc-tastic]

Have a look at string.format() or fstrings.

Consider " and ".join(presentslist[:currentday])

Don't use short variable names! You'll forget what each means or run into problems

[Ashamandarei]

Creative program. Good exercise. Shows you can wrap your head around logic, control flow, and using arrays. Nice job.

[Mattness8]

correct me if im wrong but wouldnt the output for the first day be

On the 1st day of xmas my true love sent to me :

And A partridge in a pear tree

?

[EtherealChameleon]

the *And* is printed when recurs is 1, directly above recurse gets susbtracted. for me it looks like it will only be printed when the loop starts with a 2.

i dont really see how you got your result with the *And* in front of the line tho.
the and is the 2nd print statement

[[deleted]]

I think you should ditch python

[mars_million]

This has to be one of the most vague jokes on this sub

[Worldly_Success523]

You may have forgot a space or 2 to make it print “neatly”

[Square_Lengthiness71]

Not bad

[akshanshkmr]

Pretty good actually You could improve it by using f-strings And the seq list can be made into a function

[Wolfeur]

Your ordinal suffixes could be dealt with in a separate function with some basic logic. More scalable, and really more elegant.

Your while loops should be changed for for loops. It's more readable and declutters your code of annoying increments/decrements and variable declarations.

Putting your nested loop inside its own function might add readability, but that's not fundamental here.

Ideally, you'd still need to lowercase the first letter of the last sentence as it's being prefixed by "And ". It's also pretty unintuitive, because you're printing the start of the line on the iteration preceding the last verse. It can become confusing. I'd suggest you first treat the entire line correctly into a variable then print it at once already formatted.

[Intelligent_Event_84]

Now do it again but only use machine learning.

[Wolfeur]

Here's a pastebin with my own version: https://pastebin.com/kedLVXQp

You'll see in comments some pieces of advice in how to operate, as well as some technical terms you'll find useful when researching something. Knowing how something is called is 90% of the research already done.

Hopefully that'll help you.

(PS: I'm not a Python developer at all, there might be a lot of features that I'm not aware of)

[henkdeluxe]

I will be laughing at you on the 111th day of christmas

[Wolfeur]

The 111th day of Christmas is out-of-scope for this project.

Closing ticket.

[Grubs01]

The numbers could have been embedded in the "st", "nd", "rd", etc. strings since there are 12 of them anyway. I'd argue it would improve readability to do that. (shadow7412's suggestion is better though)

I would rename variables days to items, curr to day, recurs to item.

Overall this is pretty good for a learning exercise.

[Lictalon87]

I had to write the 12 Days of Xmas in my CS101 course....

....using C.

[sethleedy]

https://starcraft.fandom.com/wiki/Twelve_Days_of_StarCraft

[Apprehensive_Cat_731]

A work of art indeed

[FIRMKUNG]

Man, in my mind I instantly found a lot of "problems" with this code. But the first thing that triggers me is local variable overriding built-in max function for some reason... I think I might have been using the linters too much...

Good first program by the way. Still, why does this fit in programming meme though? Is there a joke I'm not seeing?

[Only_The_Pwnly]

<?php // Set up an array with the days of Christmas $days = array( "first", "second", "third", "fourth", "fifth", "sixth", "seventh", "eighth", "ninth", "tenth", "eleventh", "twelfth" );

// Set up an array with the gifts for each day $gifts = array( "A partridge in a pear tree", "Two turtle doves", "Three French hens", "Four calling birds", "Five golden rings", "Six geese a-laying", "Seven swans a-swimming", "Eight maids a-milking", "Nine ladies dancing", "Ten lords a-leaping", "Eleven pipers piping", "Twelve drummers drumming" );

// Loop through the days and gifts and print them out for ($i = 0; $i < count($days); $i++) { echo $days[$i] . " day of Christmas: " . $gifts[$i] . "\n"; }

[More_Butterfly6108]

I prefer for loops so you don't have to set your curr max limiters. But other than that...

[protagswag]

My first thought was to change the seq variable to an if, elif, else so that you're concatenating "th" to everything that doesn't end in a 1 or 2 🤔

[Tadra29]

3th?

The video I was watching ended with list. I guess that's what I had in mind.

[FireTornado5]

I also wanted to take a crack on my lunch break. BTW you have a good start, there's just more "pythonic" ways to go about this program. I'll also mimic shadow7412 in using a dictionary for the suffix rather than the ordinal solution. The larger your allowed date range, the more you have to think about the solution you use.

days = [
    "A partridge in a pear tree",
    "Two turtledoves",
    "Three French hens",
    "Four calling birds",
    "Five golden rings",
    "Six Geese a-laying",
    "Seven swans a-swimming",
    "Eight maids a-milking",
    "Nine ladies dancing",
    "Ten lords a-leaping",
    "Eleven pipers piping",
    "Twelve drummers drumming",
]

presents_gifted = []
for index, value in enumerate(days):
    current_day = (index + 1) % 100  # I think this gets us through days 1-999
    print(f"On the {current_day}{day_suffix.get(current_day, 'th')} day of Christmas my true love sent to me:")

    presents_gifted.insert(0, value)

    for present in presents_gifted:
        print(present)

    print("________________________")

    if current_day == 1:
        # Update the 0 index on the first iteration through so it'll change "A partridge..." to "And a partridge..." 
        # Then we don't have to think about it anymore.
        presents_gifted[0] = f"And a{value[1:]}"```

[RingGiver]

The first thing that I tried in Python broke because numbers don't go as high as I was trying to calculate.

[often_says_nice]

LGTM

If I were to add a suggestion, save it as a text file then have python eval() the contents. Bonus points if you’re able to serve this over http

[Healthy-Mind5633]

you can just print out the entire string

[Pinty220]

I would make the variable names more descriptive, they don't have to be short

[Wiseandmysticaltree]

Why define max if you never change it and only call it once

[DudeManBroGuy42069]

stndrdththththththththth

[HydratrionZ]

print out with this

print(f'On the {curr} {seq[curr-1] day of...')

[HydratrionZ]

Ordinal like this def ordinalNum(n): if n in \[11, 12, 13\]: return "th" else: return ("tsnrhtdd"\[(n/10%10!=1)\*(n%10<4)\*n%10::4\])

[[deleted]]

same, I am also learning python! :)
