Coding Style Guidelines

PEP 8 — the Style Guide for Python Code

Recommendations

Spaces vs TAB
- indentation: recommended 4 spaces
Code layout
- 79 characters per line
- surround top-level functions and classes with two blank lines
- surround method definitions inside classes with a single blank line
- use blank lines inside functions to show clear steps.
Comments
- block and inline comments: start each line with a # followed by a single space
Whitespace in Expressions and Statements
- surround binary operators and multiple conditions statements with a single space

Recommendations

Surround docstrings with three double quotes on either side:
```
"""This is a docstring"""
```
Write them for all public modules, functions, classes, and methods.

Put the """ that ends a multiline docstring on a line by itself:

"""Solve quadratic equation via the quadratic formula.
A quadratic equation has the following form:
    ax**2 + bx + c = 0
"""
