In Python 2, the 'print' statement is not a function, and therefore it is invoked without parentheses. However, in Python 3, it is a function,.

From Today’s newsletter:

Growing up, we had to memorize the spelling of words like “return,” remember that 12 x 12 = 144, and recall the conjugations of tener . Coding is not so different, having to memorize specific syntax, rules, and commands. Drivers c2-05. And in coding, you’ll get an error if you misspell return , so it’s important to remember the details.

Python 2 Cheat Sheet

But coding should be less about rote memorization and more about understanding the principles at work. So to help you focus more on deeper understanding, we created Codecademy Cheat Sheets.

You can refer to a Cheat Sheet when you’re building your next project or querying a new data set. We also made them downloadable as PDFs, so you can take them with you anywhere.

We currently have cheat sheets for the following courses:

More to come in the future. You’ll find them at the end of each relevant lesson.

This document is a quick cheat sheet showing how the PEP 484 typelanguage represents various common types in Python 2.

Note

Technically many of the type annotations shown below are redundant,because mypy can derive them from the type of the expression. Somany of the examples have a dual purpose: show how to write theannotation, and show the inferred types.

Standard “duck types”¶

Basic Python Cheat Sheet

In typical Python code, many functions that can take a list or a dictas an argument only need their argument to be somehow “list-like” or“dict-like”. A specific meaning of “list-like” or “dict-like” (orsomething-else-like) is called a “duck type”, and several duck typesthat are common in idiomatic Python are standardized.

Decorators¶

Decorator functions can be expressed via generics. SeeDeclaring decorators for the more details.
