Python has styling conventions. These styling conventions are defined in the Python Enhancement Proposals (PEP8). Here are the condensed version of the rules:

• Indentation should be done using spaces and not tabs.

• Indentation is done using 4 spaces.

• Python files are UTF-8 encoded.

• 80 columns is the maximum for code per line.

• Each statement is to be written on a line of its own.

• Variable names, function names, and filenames are all written in lowercase. Underscores are used when separating words (aka snake_case).

• The names of classes are capitalized. If the name of a class is more than one word, use CamelCase.

• The names of packages are written in lowercase and no underscore is needed at all.

• Variables that are constants are written in uppercase.

• Make sure that variables have names that have meaning (e.g. get_user).

• Leave a space when dealing with operators (e.g. a + b).

• Whitespace that is unnecessary should be removed.

• Leave a blank line before writing a function.

• When writing methods in a class leave a blank line between them.

• Make sure to use blank lines inside functions and methods in order to keep related blocks of code separate and make your code more readable.
