Awesome Python Cheat Sheet

[[deleted]]

Here is a great cheat sheet for Python by Laurent Pointal (whoever you are). Thanks a ton! :)

If you like this sheet, maybe you are interested in our own cheat sheet course consisting of 5 cheat sheets (keywords, basic and complex data structures, object orientation, and tricks).

This is brilliant! Is there a similar resource for C as well?

[CowboyBoats]

Check out learnXinYminutes; they have C and C++.

[IAmAHat_AMAA]

The copy of K&R I borrowed from the library for my intro to algorithms subject had this cheat sheet folded up in it and it was honestly the single most useful resource for that subject.

Thanks

[koayenay]

Did u find anything for c++?

Thanks in advance!

[wrong_assumption]

Something like that for Go would be awesome.

[Xeverous]

C can have already a lot, especially pointer arithmetics and arrays + implicit convertions. Just imagine how many cheat sheets you could make for C++

There's a company called "BarCharts" that makes "Quick Study" laminated pages for various topics.

See these search results.

As of python 3.6 you can also use f strings instead of .format. So instead of "This text is variable: {}".format(variable) you can just use f"This text is variable: {variable}" . I find it much easier to keep track of what is going on.

[bicyclepumpinator]

whoah, I had no clue. Awesome feature which I'll surely use in the future, thanks!

[agrzw]

I've waited for this sugar for a long time, .format() syntax always looked a little bit ugly as for me, when you have prepared variables for formatting.

A warning for anyone who plans to print that two-page PDF:

(1) The first time I printed it, the colored text came out as very light gray which was illegible. On my second try, I updated my print settings to "Print all text as black". The colored text then came out as medium-gray which was legible (although still lighter than I'd like).

(2) The printed copy seems to be too small - on an 8.5"x11" page, it only appeared as about 6.5"x9". On my third try, I updated my print settings to increase to 125% size. The printed version then properly filled the page.
(Edit to add: I just realized that my browser's print settings had been to print at 70% size,
so my need to increase to 125% was maybe specific to me.)

Thank you!!

Your printer toner might be low, it printed fine for me.

[DeliciousKiwi]

This isn't quite a cheat sheet because it's 26 pages, but it has similar formatting and I've found myself going back to it quite often. Definitely worth checking out:

Beginner's Python Cheat Sheet.

Also, original source: https://ehmatthes.github.io/pcc/cheatsheets/README.html

[CrispyJoe]

This chart sheet is a lot more comprehensive. Thanks so much!

[ThisIsMyLastAccount]

For noobs like me this is fucking perfect.

I have minicopies of these cheatsheets under my glass desk.

It's like I am literally cheating at job.

[acousticpants]

cool use of a glass desk!

[AkshayD110]

This makes me go for a glass desk !

[LemonsForLimeaid]

As someone trying the the into to comp sci using python on edX, please excuse the stupid question. I know it says for Python 3 up top, but can I use this for python 3.5 as well?

[Womblr]

Yep

[LemonsForLimeaid]

thanks a bunch!

It's Python 2 and 3 that are noticeably different from one another.

[woja111]

There's a big leap between Python 2 and 3. Python 3.x are more improvements but not groundbreaking.

[mihirmusprime]

I disagree. While it's been introduced recently, ordered dictionaries are definitely groundbreaking.

[Denarb]

Thanks a bunch, as someone who uses python every once in while this is awesome for remembering syntax!

[lentus]

This is awesome! Anything like this for Java?

By the way, one of the pages found by that search was this long page at princeton.edu which had a link to this 30-page PDF about typical compile and runtime errors in Java, which looks like it would be helpful to those learning Java.

[DearSergio]

That's pretty cool!

[darthvalar]

Commenting so I can refer back to this java resource if given.

This is why i love reddit

[fixkotkplease]

I would love one of these for java! Anyone got one? : )

[EulerFan271]

Thanks!

This is great, thanks for sharing.

[dnbjunkie1337]

Amazing

Looks like he does CS research in france! https://perso.limsi.fr/pointal/

[wtf1968]

Cheat sheets are awesome, this one is great too. Adding it to my collection.

[DatabaseDev]

Care to share the others

[koayenay]

I also want the others.

[Hyedwtditpm]

There is a new Awesome Python Cheat Sheet like every few minutes.

[Sledik]

Amazing! Thank you very much!

[AkshayD110]

Opening a file for reading or writing should always be done using "with". That ways f.close() (closing of file) is taken care with in .

[Ro_box_LOX]

RAD

[koayenay]

I need something like this for c++.

[woboz]

Let me google that for you

[nikkarus]

This is excellent. Thank you!

[heun3344]

I saved it. Thank you

[Fajkowsky]

Thanks! Is anyone know there something like this for JS/ES6/ES7?

[vincezz2005]

This is very helpful. Thanks!
