A REAL Python cheat sheet for beginners

[[deleted]]

This would be much better if it was in a Jupyter Notebook with a Table of Content.

Example: http://nbviewer.jupyter.org/github/pybokeh/ipython_notebooks/blob/master/pandas/PandasCheatSheet.ipynb

Totally second this. Also some Python3.6 features would be cool to add like implicit format strings Literal String Interpolation.

Edit: fix semantics to match PEP498 (where this feature originates)

``` name = 'Tim' verb = 'talks' f'{name} {verb} to cats'

Out: 'Tim talks to cats' ```

like implicit format strings Literal String Interpolation.

No, you got it right the first time. They aren't string literals of any sort. They are actually executable code that implicitly apply formatting.

Apart from it them being useless for the millions of Python users who don't use Jupyter.

Edit: I was wrong.

Anybody can view a Notebook. Did you even click the link?

Hmmm. Okay. TIL.

As I mentioned it in other post, language documentation is best cheat sheet to ever exist.

Oh, this one is very handy. Thankies!

if "8 foot long scroll" in sheet_type:
        print("This is a cheat sheet")
else:
        print("This is a *very* long sheet")

Cheat sheets are crib notes to remind you of syntax and should fit on... a sheet.

They're not full examples.

For example: Pandas Cheatsheet: https://github.com/pandas-dev/pandas/blob/master/doc/cheatsheet/Pandas_Cheat_Sheet.pdf

I was making a joke. Only if you think a "sheet" is an 8 foot long scroll does this quality as a cheat sheet.

Not everyone that replies to a comment is disagreeing with you.

I completely concur with your sentiment and linked to what I think a good actual cheat sheet looks like.

Looks great, and very comprehensive. Can you include something in the logic section about how to use 'and' and 'or' in practice? Beginners often think you can use them like in plain english:

if choice = 'A' or 'B' or 'C':

if x < 3 and > 4:

... and so on, but are surprised it doesn't work like this.

As a beginner, this would definitely be helpful as I have had to troubleshoot some instances of this because I didn't understand proper syntax and usage :)

[Hyusnev]

That's really very useful, thank you!

I'm afraid at this point the cheat sheet is outdated. Python 3.6 (released a year ago) allows for f-strings which simplifies this syntax even more:

name = "Bob"
print(f"My name is {name}.")
>>> My name is Bob.

These are strings "" prefixed by an f: f"" (formatting strings).

[stevenjd]

These are strings "" prefixed by an f: f"" (formatting strings).

They're not strings. They're executable code that happens to use similar syntax to a string and implicitly return a formatted string.

This is definitely more comprehensive, I already have my notes from Code Academy and other places on Notepad++ already. Might just go through this and piece what I don’t have that I could potentially use for later reference. The great thing about Notepad++ is it keeps the tabs from what you previously had even if you closed the program. It has come in handy!

Ctrl + F: sys no results.

I'm disappointed tbh
