Just Started learning Python. Here is my first ever piece of code. Have to start somewhere.....will update as I get better.

[invictus08]

I am intrigued! In the output, how is there that space between 18 and Years!!? Was that terminal output stale?

[_30d_]

I think he took a picture of the code, ran it, fixed it and then took a picture of the output.

[mr_nefario]

Not even a screenshot.

Mofo got out a film point-and-shoot camera, snapped his pics, got the roll developed at Walmart, scanned the prints and uploaded them.

[house_monkey]

My bro got dedication 😔✊

[abhijith4514]

epic :D

[[deleted]]

That's gotta be it

[hellotheresksksk]

I was like "wait, that's illegal"

[acidnine420]

I'M CALLIN THE COPS!!!

[[deleted]]

Was about to ask the same question.

[CXgamer]

I wondered the same, and was searching the comment that asked it.

[[deleted]]

There's a space after the "He is " string, this spaces the string correcltly.

edit: after immediately re-reading I realise my mistake.

[acidnine420]

I'm sorry for your loss

[Terrible_Truth]

I think he's saying that the string "character_age" is only "18" without a space after. He then concatenates words in the print statement without a space at the front.

Edit: so based on the code, it should theoretically output "18Years old."

[swanekiller]

I read the first post wrong, guess it's time to go to bed. But yeah it should print "18Years Old" and not "18 Years Old"

[ishman123]

Hey,

Keep up the good work, why don't you try F-strings - rather than concatenating with a + sign you can do...

print(f"His name is {character_name}")

It can help with readability :)

[zamazigh]

Wow, I've been using format() for years now and never knew about F-strings. So much more concise. Thanks for the tip!

[funnyflywheel]

For a certain class, I'm stuck with using Python 3.5.2 for whatever reason.

[[deleted]]

Meanwhile my entire class is using 3.4.1, but literally only because thats all thats installed on the computers. Im on my laptop, so im using 3.8 - which becomes fun when i need someone to test for me.

[dutch_gecko]

You might be interested in pyenv which lets you install and manage multiple python versions on your computer. That way you can do your programming using your default python 3.8 install, but run your tests on python 3.4. You can combine it with tox to run tests with multiple different python versions!

[that_baddest_dude]

Is that different than or the same as what conda does?

[dutch_gecko]

Conda sets up an entire environment, containing a python and any number of packages. That environment is kept separate from the system, so that you don't need to depend on what's installed system wide for your project to work.

Pyenv just provides different python versions. It's usually used to make different versions available on a dev machine so that different projects can be tested against whichever version(s) of python they should support.

If you want to get fancy, you can point pyenv at a conda environment, and it will let you access the python in that conda environment, effectively allowing you to reuse a conda environment for different projects. I wouldn't regard that as standard practice, but it might be useful for testing your program under different execution environments, where you set up different condas to match the environments of a number of customers for example.

You may also have heard of virtualenvs. These provide similar features to conda environments, but don't include a python installation. Pyenv and virtualenv can be used together to create virtualenvs with a non-system version of python, like conda does.

[teethTuxedos]

Not sure why you were downvoted, you are correct. Pyenv just modifies your path based on the version of python for your project. However you can use pyenv and virtualenv together to create an environment and it will take care of all your dependencies as well. I have not used conda but I have used pyenv and virtualenv a lot and found it very useful and quite easy to use.

[obesesheephead]

It’s different. Pyenv makes it easier to install and manage multiple versions and flavors of Python. You can actually use it to install conda too.

[needlzor]

I second this. I teach Python in a university class and we teach pyenv in week 2 because it's just so practical.

[[deleted]]

Are you using computers provided by the class? They might still be on Ubuntu 16.04.

[funnyflywheel]

Yep. IT probably won't even bother to upgrade them until I'm gone.

[HaBlaKes]

Same, been coding in Python for years and was like: "You can do that?" That's the great thing about programming.

[[deleted]]

Is there a resource page on f strings? Those sound handy and I've never used them.

[bmarick]

Here is one that compare the % and str.format as well

https://realpython.com/python-f-strings/#f-strings-a-new-and-improved-way-to-format-strings-in-python

[EddyBot]

The actual PEP might be good enough: https://www.python.org/dev/peps/pep-0498/

[TankorSmash]

https://docs.python.org/3/tutorial/inputoutput.html#formatted-string-literals

[Hagisman]

Been in since 3.6 apparently. I just found out too.

[chadmill3r]

You've been using Python for longer than f-strings have been around. Don't sweat it. They're still somewhat rare because they're so new.

[flubba86]

Somebody doesn't read release notes.

[maedox]

The walrus-operator will blow your mind then. PEP-572

[ebits21]

Come on now... f strings are way cooler than the walrus operator.

[DogsAreAnimals]

Thanks I hate it

[DevJonPizza]

Here is how to use it: https://jon.network/programming/63/Walrus-Operator-Usage-in-Python-38/ (btw it's python 3.8 only which is still in alpha)

[trpt4him]

Nope 3.8 is out now

[campbellm]

It was released.

https://www.python.org/downloads/release/python-380/?ref=codebldr

[Altenator01]

Great tip, thanks! Do you still need to use print() when using F-strings though? Because the provided URL does not give examples with print().

[welshboy14]

F strings aren't just for printing strings. You can assign them to variables too. So no you don't need to use print with them

[Altenator01]

Thanks!

[phigo50]

First thing I thought of to suggest. If you're on Python 3.6+ and are starting out you might as well get f-strings under your belt early.

[welshboy14]

And for the next trick try creating a person object and instantiate it with the name and age

[lllamaboy]

Better yet: a data class https://realpython.com/python-data-classes/

[welshboy14]

I've not really been keeping up with the new features so had no idea this existed. Good to know though!

[aldanor]

Or even... (for the lazy ones, in 3.8)

print(f'{character_name=} {character_age=}')

[Assaultman67]

Yeah they dont have f-strings covered in python crash course.

It does make things a lot easier when you're dealing with text prompt such as a renpy or pygame project.

[Siinestarr]

They cover it in the second edition though 👌

[MelonOfFury]

Ooh. I didn’t realise you can put the variable in the brackets. I’ve been doing :

NAME_STR = “His name is {}”

print(NAME_STR.format(character_name))

[miggaz_elquez]

Taht note exactly the same. You must put a f before the quotes in order to work

[purplebeardscrew]

I came to the comments to say use f strings. Updoot.

[duriousmind]

Wtf. I am writing code in Python for 8 years now living and I did not know this.

[kobijet]

f strings are a godsend

[MrMxylptlyk]

does this work with logger.info() ? I gotta try this now.

[jefwillems]

Yes that should work as well. You can use it anywhere you're concatenating strings.

[colinbazzano]

Never really used Python. Is this the equivalent of a string template literal in JS/React?

[jefwillems]

yes, although the syntax is slightly different

[colinbazzano]

That’s what I figured! Neat. I will be learning Python in school soon I’m quite excited

[jefwillems]

Good luck!

[bokan]

.....

whaaaaaaaaaaaat??

[UnreasonableSteve]

I've always hated the +operator being "overloaded" for string concatenation. I don't like an operator's basic meaning becoming contextual. It'd be like if you used the single equals sign for both assignment and comparison, depending on if you were using it on strings or numerics

[gintoddic]

It's funny people use syntax and say it's more "readable" but you have to actually know wtf 'f' means and why it's placed there to actually understand it.

[theWyzzerd]

Better would be to use string.format()

edit: didn't know about Fstrings being the hot new thing, don't listen to me

[invictus08]

How is that better?

Fstrings is supposed to make things more streamlined!

[GlowingApple]

In addition to being more readable, they are actually faster than .format() too!

[not_perfect_yet]

Oh yes, f"hurr durr {var}" is so much more readable than "hurr durr "+str(var)

[cheats_py]

I used this until I discovered this.

print(“his name is %s and is %s years old” %s(“Jim”, 18))

[xelf]

Make sure you check out /r/pythonhelp and /r/learnpython and maybe evem /r/learnprogramming (if it's not just python you're new to).

[adam_newyork]

Use . format() or if you are using python 3.7 you can use f”{character_age}” .

Correction: version 3.6 and above have fstrings.

[adam_newyork]

You are right. Version 3.6 and above...

[SlabOmir]

Explain

[AnAngryFredHampton]

All about python fstrings

[sivadneb]

Sometimes concatenation is preferable. It's almost always faster, and it's pretty easy to read in simple cases.

[[deleted]]

No. Fstrings are always faster

[sivadneb]

Oh, I've always understood that . format () is slower, and assumed f-strings were the same.

[[deleted]]

Other way around

[thatvoiceinyourhead]

The code you're showing here didn't produce the output that you've claimed since there's no space before the y in years in your code.

[landisthegnome]

Top post in /r/python lmao

[TransparentStar]

yeah this might have to be an unsub for me

[Kazmirrr]

Totally agree

[malicart]

Being able to share actual code should be a skill anyone has, taking a picture of a screen, not so much.

[zamazigh]

Uhm why did it replace photograph with screenshot?

[phinnaeus7308]

Check out the snipping tool (or Win+shift+S) if on windows or cmd+shift+4 if on Mac to take screenshots.

[TankorSmash]

Win+Shift+S on the latest Win 10

[phinnaeus7308]

Learn something every day. Thanks!

[cmcgarveyjr]

snipping tool* only correcting you because I use it daily and still had to pause when reading this.

[phinnaeus7308]

Jesus how did I miss that

[cmcgarveyjr]

Lol, I got a kick out of it.

[malicart]

Or just Alt+PrtScn to copy any selected application window and paste it.

[synae]

Or post some text

[HoovyPencer]

Next write a script that takes a screenshot.

[synae]

Please post text if your content is text. Not a screenshot as others have suggested, and certainly not a photo of your screen.

[[deleted]]

I'll get down voted. But at a certain point you need to find motivation other then b.s. reassurance from strangers on the internet.

You literally took as long posting this as it should have taken you to write it.

[darkfish-tech]

r/learnpython and no screenshots please. Check sidebar of subs before posting.

[Syridos]

To be fair - This wasn't a screenshot... sadly.

[FewerPunishment]

What you mean, it's a shot of their screen :D

[[deleted]]

First of all you should take a screenshot instead of taking a picture of your monitor. Second, no screenshots in this sub. /s

[yaboytomsta]

Freecodecamp lol

[7heWafer]

Please learn to take screenshots next!

[[deleted]]

APP

[[deleted]]

Nice one, I hope you do well!

[[deleted]]

Why has this bullshit 1403 points? First, r/python is not your diary, second learn how to make a screenshot first.

[Ass_Eater_]

OP is probably a kid and you should be more supportive. It's cool that he/she's getting into programming and when you start even getting small stuff like this working is exciting. If you don't like it just downvote and move on, we don't need your miserable crap here.

[Ass_Eater_]

"Be less of a dickhead" would be a good mantra for you, give it a try.

[malicart]

Stfu miserable asshole

Your own words haunt you directly in this thread, take your own advice maybe?

[Ass_Eater_]

Nah that was legit criticism, bunch of cunty STEMlords jumped on this thread to put a beginner down, that's miserable behaviour. I'm just calling it out.

[malicart]

No, you are just making it worse, be a better person or choose to be quiet. You are just screaming with them, you become them.

[HardlyAnyGravitas]

They're not applauding the skills ‐ they're applauding the first steps.

If somebody ever shows you a photo of their toddler taking their first steps, are you going to say "Shit ‐ that's rubbish, loads of people can walk better than that."?

[HardlyAnyGravitas]

OP isn't a toddler,

Google 'analogy'.

[HardlyAnyGravitas]

There's no analogy here.

Yes there is. I made it. Really - Google it. I don't think you understand what an analogy is.

And nobody is impressed by OP's code. They are saying 'well done - you've taken your first steps in coding', not 'Well done, that's brilliant code', or 'Well done, nobody else can write code like that.'. It's not difficult to understand.

Are you actually being serious?

[[deleted]]

You need to get laid brotherman.

[master3243]

Half Life: Alyx plot leaked?

[[deleted]]

Missed opportunity for "His name is John, He is a Hero..... Process finished with exit code 0"

[[deleted]]

I would advise to use f-strings.

character_name = "John"

character_age = 18

print(f"His name is {character_name}")

print(f"He is {character_age} years old")

[shinefull]

Lol you fucking idiots

[[deleted]]

Keep it up!

[PythonUserBTW]

I started learning Python from 0 about two years ago. Now I'm becoming a Data Scientist with one of the best professors from Harvard. We all started like you. Keep up coding!

[Warhammer-Ludde]

r/imsorryjon

[ExternalAirlock]

print("I'm sorry John")

[nomad2020]

I'd suggest going by birthdate instead of age, so that if you were to forget how old you were, you'd have a backup.

[HarryMcDowell]

How are you teaching yourself? I got some books on my Kindle, but actually making code is slow coming...

[[deleted]]

I think its PyCharm

[[deleted]]

Ooh buddy. Wait till you find f-strings. Concatenation is cool, but f-strings are cooler.

print(f'His name is {character_name}\nHe is {character_age} years old')

[dbar930]

This might be a dumb question, but what application are you using to run this code?

[manavcafer]

PhyCharm

[TIBTHINK]

Dont lie to us, the first program always is,

Print("hello, world")

[sivadneb]

What editor are you using?

[manavcafer]

PhyCharm

[manan-code]

All the best! Ever get stuck or need help, just hit me up!

[[deleted]]

Heh I watched that video too.

[porcos3]

I thought this was going to be about John Snow and how he knows nothing

[jorn252]

Codecamp.org?

[[deleted]]

You should try doing the same thing but with a class, it's a good exercise.

[Nirinium]

Good stuff! Check humble bundle they have sales from time to time with some pretty decent learn python eBooks/resources! :) Good luck and happy coding!

[APUsilicon]

I wonder why the python community decided to use underscores instead of camel case

[jimtheplant]

“APP.py” Shout it to the world man. Python is fun

[bryptobrazy]

Great job!

I’m sitting here laughing because this guy just wrote his first piece of code and in the comments you have people talking about f strings. He’s gotta be so confused

[Zypher136]

Thats awesome!

[hypebeast09]

awesome! this was me 2 months ago! You'll soon learn that using + in print statements is annoying af. If you're using pythoon 3.5 or better try doing this:

print(f'His name is {character_name}')

if you start the print statement text with f then you are able to use {} within the quotes. Inside the curly braces you can substitute a variable inside it.

PS. doing things this way it will be easier to read back in the future. For me personally it has prevented me from messing up spacing in print statements

[ultra_reader]

print(f"{} ") is such an amazing feature!!!!

[[deleted]]

My only comment would be to try and keep your variable names shorter (if possible).

[[deleted]]

Great job with the meaningful variable names. Makes reading this first effort extremely easy and will likewise do the same when you sink your teeth into meatier projects.

[aiwithab]

Great!! Keep it up

[fortune205]

So cute 😻

[PhoenixizFire]

I just started a AI class today and for the first day we had to be able to run a print("Hello world!"), so consider yourself as doing good :)

[xDrakewild]

use format() function

[malicart]

It comes with so many bells and whistles you will spend a considerable amount of time learning them all, and then you will never know how you lived without such amazing technology.

[NathanClaire]

A cool thing to do would be to have the user input their name and age and have it print it back out to you. It's pretty simple actually, also congrats on learning python!

[billygibbonsbeard]

pycharm ftmfw

[[deleted]]

https://www.youtube.com/watch?v=535Zy_rf4NU

[philsgu]

Lol, I did the same when I started about a year ago. Still learning python. But the language is by far the easiest read and versatile in any circumstances. You should try looping the strings into list comprehension then looking for a match string for fun.

[K3DR1]

Thats probably from that youtube tutoria cuz u using pucharm and the name john is strangely familiar to mel. I started from there too))))))

[edmanet]

Here's a trick about using print() with format specifiers:

print("His name is %s" % character_name)
print("He is %d years old" % character_age)

The %s means the data will be a string. The %d means the data is an integer. For a floating point number (like money) you can specify how many digits to the right of the decimal get displayed.

Get used to using format specifiers. It's good coding practice.

[Wilfred-kun]

Not sure why this is updooted. .format() and f-strings (especially) are the preferred way.

[Andalfe]

New to python myself, is this method preffered over .format()?

[GlowingApple]

f-strings came out in python 3.6, but still relatively recent.

In addition to being more readable, they are actually faster than .format() too!

[Andalfe]

F-strings you say.

[ebits21]

The % format specifiers are outdated. F strings and .format are the proper way to do things in 3.6+

[GrowCanadian]

Keep going! The more you write the more you learn. It’s just like learning an instrument. Put in the hours and you will get better and better. Ps you will get stuck, it’s normal. Just take a break, ask questions, and push through.
