Write Python Code Properly!

Welcome back to another video! In this video, I am going to be showing you the proper way to write Python code. What I mean is that I will be going over the proper python conventions and the most important parts of the python style guide known as PEP8. There is a lot in PEP8 but I'll only go over the most common mistakes made.

Cases:
snake_case
lowerCamelCase
UpperCamelCase / PascalCase
SCREAMING_SNAKE_CASE

[bassam.]

For such a versatile, and useful language, many of Python's conventions are absolutely assinine.

[huantian]

Random things: order of imports is recommended to be future imports, builtin packages, 3rd party modules, project specific imports, each separated with a newline.
When you have a keyword argument with a typehint, you add the extra spaces: def foo(str: arugment = “hi”):

[exstasis]

I love the way that snake case looks in PEP-8. At first I was not excited about having to reach my fingers to do the awkward _ characters, but really, I only need to type those when I first declare the variable. Every other time I use that variable, I can just use my editor's autocomplete and just skip all the underscore characters and then just hit tab to accept the autocomplete.

Tim I'm beginner at python and overall new to programming your videos are helping me a lot. I'm really interested in data analysis can you please make some videos on this topic

[tadiwashangwa]

I was actually researching on this thank you Tim

[ankitaburman]

You are right now my most favourite person on this planet...❤️ Thanks a ton for all the learning videos

[ncmathsadist]

If you use if foo[3:] == "bar" and you subsequently change "bar" to "barf", your code is broken unless you also edit the slice size. This is brittle. That's why Guido recommends endswith and startswith.

[roydadancegod]

Also could you cover what to do for parameter and return type and the spacing for it? For example def function(a:int, b:list) -> list

[zulucharlie]

Excellent, to-the-point summary of PEP8 convention. Thank you.

Hi Tim, i'm very new to tech and a career changer, i just want to say that the content here is one of the best explanations i've found scouring the interwebs!

[sumitpatidar]

Unconsciously I follow all pep8 style guide you have discussed in this video 😄

[TheFootballPlaya]

i didn't know about the startswith thing either, good to know. i've seen it around used a lot. question though, for function names that are multiple words, do these act similarly to variable names as in they are snake case as well, or is there some other way of denoting functions as opposed to variables? also, do we treat lambda functions any differently in this regard if they are stored in a variable?

[zachfenton]

this is awesome and explained well why these rules are used

[Markyroson]

Camel case: aka how you spot people who started in other programming languages and have a hard time breaking the habit in Python 😂

[save-scum]

What screen recording + editing software do you use? Your code is presented very aesthetically and in an easy to read/comprehend way!

[akira_asahi]

Thank you for the video. I am grateful for your time and contribution. Kind regards, Akira.

[AI-tgby]

Love your vids! Could you do any about when you would use classes because I do get confused slightly.. maybe through doing a project - that would be ace!

[Landon_Hughes]

I swear every time I look something up, you release a new video on the subject lol
Thanks!

Irony: in an article title "write proper python code" using "from os import path" as an example when Pathlib is by far the preferred solution for handling file paths
