Python docstrings are special strings used to document Python functions, classes, and modules. They provide an easy way to describe the purpose, parameters, and return values of a function or class. Docstrings are enclosed in triple quotes (“”” “””) and are placed immediately after the function or class definition.
A well-written docstring follows a standard format, often consisting of:
- A brief description of what the function or class does.
- An explanation of parameters, including their type and purpose.
- A description of the return value, if applicable.
For example:
def add(a, b):
“””
Adds two numbers.
Parameters:
a (int): The first number.
b (int): The second number.
Returns:
int: The sum of a and b.
“””
return a + b
Docstrings enhance code readability and are essential for generating documentation automatically, such as with tools like Sphinx
