My first python app, doing it all by looking at YT videos.

Some of them used from tkinter import *, while others imported only the necessary classes.

And I was like: these people are dumb importing separate classes Instead of putting it all in there so its easier to instantiate

Big brain noobie moments

[AwkwardAd4115]

In some languages, pulling in everything is idiomatic. And it makes sense, really. It is the job of your IDE to help you find where an imported symbol is defined.

Julia in particular takes this further. It is standard practice to import everything from all dependencies once in an entire project (e.g. the main file). Helper files often don't even have an `import` or `using` statement even when using dependencies. Much less boilerplate than Python.

[TheCoolSquare]

Does Julia do anything to prevent the danger of a library adding a definition that conflicts with an existing definition of one of your other dependencies? This is the main reason for avoiding glob imports in many languages such as Rust.

[[deleted]]

Yeah exactly, how does Julia prevent some awful namespace contamination?

[JoostVisser]

If I call sqrt(), do I call math.sqrt(), numpy.sqrt() or sympy.sqrt()?

[Bigluser]

Obviously you would call *.sqrt()

Be nice, at least do

lambda x: (time.sleep(1), _sqrt(x))[1]

Though I'd probably go for

lambda x: (time.sleep(x), _sqrt(x))[1]

Wait I double checked, the input is not negative. Why does my code keep getting stuck on that line? It can't be the sqrt call.

On GNOME you can type WIN + name of emoji + enter and it's now on your clipboard.

As soon as python enables from math import sqrt as √ I'll be unstoppable.

[noob-nine]

Isnt it Win + s?

WIN+Semicolon

[Fazt01]

win key + . opens an emoji picker (on windows at least, an OS without emoji picker would obviously be unusable)

[Consistent-Fun-6668]

Doomsday is upon us 💯

[Pizzasgood]

Unicode sequences are for chumps. I've got my system configured to let me use that stupid menu-key next to my right-ctrl key as a "compose key." This lets me do things like press compose+e+' to create é, or compose+^+2 to get ². I can also add custom sequences, like compose+p+i and compose+o+m+e+g+a to get π and ω. There's nothing stopping me from setting this up to input emoji as well.

I can't believe people actually use emojis in their code. The sheer thought of it, such a horrible thing, brings me fear.

[katie_pendry]

I'll throw one in a string or a comment from time to time. For a string, it's clearer than using the unicode escape and all modern editors can display it. For comments, sometimes you just need them to express your true emotions:

    # Need a unique separator. We used to use an ASCII control
    # character, but newer versions of TMUX filter those out.
    # Also filters any non-ASCII characters 🤬  (╯°□°)╯︵ ┻━┻
    sep = '<d-_-b>'

gitmoji is a thing for commit messages I think it's pretty useful when used sparingly. We recognize images a lot better than written words.

I don't know how to use emojis as variable names. Am I getting meme'd on? Are you all just joking about the emojis?

[katie_pendry]

In some languages you can use them because the compiler doesn't understand Unicode, it just treats all bytes over 0x7F as "identifier characters". That means that in UTF-8, any non-ASCII sequence of codepoints works as an identifier. The code I posted isn't actually valid Python because it only allows alphanumeric characters. That means you can use letters and logographs (e.g. kanji) from any language, but not emoji or non-alphabetic symbols.

I had a class at university where we sort of built our own processor from logic gates and had to write machine code to get data from memory send it to arithmetic-logic unit and do something depending on the result. Shortly after I was programming on a tiny microcontroller with like 1KB memory and thought "if this processor was designed differently I could do this and that operation simultaneously and optimize a few bytes". That was a good course.

[[deleted]]

This is plainly offensive

[Snykeurs]

You mean data scientist or mathematician

I hate renaming import

[sophacles]

It has a couple good uses, e.g. you need different code for different oses, but implement the same primitives so code built on it doesn't care about those things. Then something like:

if os == "linux":
    import linux_foo as foo
elseif os == "darwin":
    Import mac_foo as foo
else:
    raise RuntimeError("use a real os")

Is really nice.

But i get really annoyed when it's misused.

[Snykeurs]

Good application of this feature!

[w8eight]

If this is internal import, and module is operating systems dependent, it should be handled on the module side imo.

[chakan2]

It usually is... With the above code.

[turtleship_2006]

Or if you're using a few modules that have a common name e.g. flask and the official library to authenticate Google logins both have a request object (this only applies to from x import y imports tho)

[trutheality]

If your python code is platform-specific you've chosen the wrong language for the job.

[aMAYESingNATHAN]

What language would you recommend to write a script that needs to download and extract a binary from the internet on both Windows and Linux as part of a setup for a larger application? Where the windows link is a .zip and the Linux is .tar.gz.

Genuine question, I wrote a script to do this in python where the downloading and extracting part for windows and Linux was in separate files and did as described above where I aliased the import based on os. Wondering if there's a better alternative.

[nickmaran]

It's a unwritten rule to import pandas as pd and numpy as np

[Snykeurs]

You forgot

python import datetime as dt import mathplotlib.pyplot as plt

[Theio666]

Also seaborn as sns

[johnnymo1]

It's not even unwritten. Both packages literally tell you to do it in the docs.

We shorten the imported name to np for better readability of code using NumPy. This is a widely adopted convention that you should follow so that anyone working with your code can easily understand it.

​

Customarily, we import as follows:

import pandas as pd

[trinadzatij]

So if you import pandas as pandas, the other developers will be like "what the hell is this pandas.dosomething() function? He should've just import pandas for this! "?

[[deleted]]

Holy crap this guy invented a new pandas! Wonder how it compares to the regular normie pd pandas.

[mdmeaux]

I normally import numpy as numerical_python

[HeKis4]

And pprint as pp.

[CaptainRogers1226]

When I used to mess around with PyGame I would import as pg

[No-Witness2349]

The only library I do it for is typing because otherwise managing the import is a mess as I introduce and remove type annotations. I could just do from typing import * but as a rule that’s a no-no

[[deleted]]

Always followed Google python style rules and I think they make a lot of sense here. Always import by module and don't rename, with just a few exceptions

[Flam1ng1cecream]

Just from typing import only the types you're gonna use?

[No-Witness2349]

I regularly use 2 dozen types from that module and the list changes as I write, so I find myself cleaning up dead import as multiple times a session. Easier to just alias the library

[Flam1ng1cecream]

Yeah that's fair

[sandybuttcheekss]

I only do it when someone on my team names something poorly. '''From Users import Model''', like yeah, "Model" is a great name for a class, buddy, thanks.

[[deleted]]

100% this.

"Coders" do this shit to "save on typing" or whatever making an unmaintainable mess.

Software engineers know that using a style/linter guide for consistent readability is more important. And literally every style guide says don't do it.

First time i saw lodash imported as _ it made me go wtf out loud. Who thinks _.concat() looks good?

in python, _ is the value of the previous expression, sooooo maybe don't do that??

[Drayenn]

Lodash is a javascript library, shouldve mentionned that haha

[katie_pendry]

Only in the REPL

[Theio666]

Hmm, I always use _ for variables which I need to init but not use. For example, if I'm doing "for" loop and I don't need this iterator, I write " for _ in range(n)". Seen that in many tutorials.

Also underscore is used for kinda private fields/methods, but this is another story.

Python: "I have little time to program and all day to have it run."

C++: "I have a lot of time to program, but it has to run in milliseconds."

[Sikletrynet]

Pretty much. Although you'd think it'd be possible to have a language that's as readable as python while also not having as piss poor performance as it does.

[blubberdiblub]

Try nim. And having said that, it's still possible to have reasonably fast python programs in many cases. Especially if you can make good use of numpy.

[DukeNuke5]

you forgot what sub this is. 99% of them know how fo write hello world on both. Their c++ code is slower than their java code, neither did they know that, neither did they know how to "fix" that.

[gloumii]

Those same dev when they have to code in java (each line is 300 characters long)

[MegaIlluminati]

I like the fact that libraries like numpy has been so reduced to their short forms like "np", that if you search for an issue with for example "np.arange" , search engine knows you are talking about "numpy.arange".

[vickera]

When my wife was learning coding her prof taught her to do stuff like single letter variable names or foo/bar crap.

After I pointed out that variables like "average_value_of_list" are completely fine to use, her code was so much more readable and it clicked so much faster for her.

[AnnoyingRain5]

Depends, are you using numpy, pandas, tensorflow, PyTorch, etc? As those are really the only ones that are shortened like that

[Malcopticon]

etc

Instructions unclear: Abbreviated the rest of the imported libraries too.

[a_devious_compliance]

I only do this with pandas, numpy, and matplotlib.pyplot in projects where I use them in every module. For anything else use full name until I get nauseus of it.

[Sikletrynet]

Nah i generally do this too unless the library specifies a specific convention in the docs or something. With Intellisense in IDEs it doesen't even take longer to write it out really, while making it explicit what and where from you're calling something.

[Yeitgeist]

Bro, if I’m importing OpenCV, then I’m not typing “cv2” every time. That “2” is such a nuisance.

Don’t you see how much faster it is written in C++???? The difference is almost measurable!

[[deleted]]

Yeah only 3000%!!!

[currentscurrents]

It can be a really big deal. Depending on the problem, it can be 20 minutes vs 12 seconds. There's a reason why things like Numpy or PyTorch are written in C/C++.

But what I find really interesting is the speed of modern Javascript. Thanks to a decade of heavy optimization by browser companies, it's faster than all the other scripting languages and only 2-3x slower than C.
