Python naming conventions cheat sheet. How to Write Beautiful Python Code With PEP 8 – Real Python, Naming Conventions. “Explicit is better than implicit.” — The Zen of Python. When you write Python code, you have to name a Python Naming Convention. The style guide for Python is based on Guido’s naming convention recommendations. This document gives coding conventions for the Python code comprising the standard library in the main Python distribution. Please see the companion informational PEP describing style guidelines for the C code in the C implementation of Python 1.
Python is a general-purpose language — sometimes referred to as utilitarian — which is designed to be simple to read and write. The point that it’s not a complex language is important. The designers placed less of an emphasis on conventional syntax, which makes it easier to work with, even for non-programmers or developers.
Furthermore, because it’s considered truly universal and used to meet various development needs, it’s a language that offers a lot of options to programmers in general. If they begin working with Python for one job or career, they can easily jump to another, even if it’s in an unrelated industry. The language is used for system operations, web development, server and administrative tools, deployment, scientific modeling and much more.
Python in this cheatsheet is in Python 3.x .
For users that are using Python 2.x or more than 3.x , make sure you check the internet first.

Maximum Line Length¶
Pep8 Cheat Sheet 2019
Limit all lines to a maximum of 79 characters.
There are still many devices around that are limited to 80 characterlines; plus, limiting windows to 80 characters makes it possible tohave several windows side-by-side. The default wrapping on suchdevices disrupts the visual structure of the code, making it moredifficult to understand. Therefore, please limit all lines to amaximum of 79 characters. For flowing long blocks of text (docstringsor comments), limiting the length to 72 characters is recommended.
The preferred way of wrapping long lines is by using Python’s impliedline continuation inside parentheses, brackets and braces. Long linescan be broken over multiple lines by wrapping expressions inparentheses. These should be used in preference to using a backslashfor line continuation.

Backslashes may still be appropriate at times. For example, long,multiple with-statements cannot use implicit continuation, sobackslashes are acceptable:
Another such case is with assert statements.
Make sure to indent the continued line appropriately. The preferredplace to break around a binary operator is after the operator, notbefore it. Some examples:
