Comments in Python are the lines that are ignored by the interpreter during the execution of the program. It can enhance the readability of your python code and help other programmers to understand the code easily.

Types of Comments in Python

Here are three types of comments in python. They are:

• Single-Line Comments
• Multi-Line Comments
• Docstring

Single-Line Comments

Python single-line comment starts with the hashtag symbol (#) with no white spaces and lasts till the end of the line.

Example:

# This is the first single-line comment in Python

print("Hello, World!") # This is the second comment

This example contains tow single-line comments.

Multi-Line Comments

In Python, multi-line comments can be created using triple quotes (""" or ''' ) or by using consecutive single-line comments with the hash symbol(#).

Using Triple Quotes

Triple quotes are often used for multiline comments. The text enclosed within triple quotes is ignored by the interpreter if not assigned to a variable.

Example:

"""
This is a multiline comment
using triple quotes
It spans multiple lines
"""
print("Hello, World!")

Consecutive Single-Line Comments

Another way to create multiline comments is by using consecutive single-line comments with the hash symbol (#).

Example:

# This is a comment
# written in multiple lines
# using consecutive single-line comments

print("Hello, World!")`

Docstring

Python docstring is the string literals with triple quotes that appears right after the definition of a function, method, class, or module. It is used to describe what they do. In Python, the docstring is then made available via the __doc__ attribute.

Example:

def multiply(a, b):
    """Multiplies the value of a and b"""
    
    return a*b

# Print the docstring of multiply function
print(multiply.__doc__)
