Methods to Comment Out Multiple Lines in Python

There are primarily two methods to comment out multiple lines in Python. These methods are straightforward and provide programmers with the flexibility to temporarily remove certain blocks of code from execution, which can be particularly useful during debugging. Here’s a breakdown of the two methods:

Using Hash Character

To comment out multiple lines of code in Python, one common practice is to prepend each line with a hash (#) character. This method technically creates multiple single-line comments, as illustrated below:

# print("Hello world")
# print("Hello universe")
# print("Hello everyone")
print("Hello campers")

In the code snippet above, the first three print statements are commented out, so only “Hello campers” will be output when the code is run【6†source】.

Using Multi-line String

Alternatively, multi-line strings, enclosed in triple quotes (""" or '''), can be used to comment out multiple lines in Python. This method treats the comment as a string, thus ignoring it during execution:

"""
This is a comment
written in more than just one line
"""
print("Hello, World!")

In this code snippet, a block of text is turned into a multi-line comment, allowing “Hello, World!” to be the only output when the code is run【8†source】【9†source】.

Methods to Comment Out Multiple Lines in Python

Commenting out code is a common practice among developers to either document the code or to temporarily disable certain parts of the code. In Python, there are primarily two methods to comment out multiple lines of code. This section delves into these methods, providing a clear understanding and comparison to help you choose the best method for your coding needs.

Using Hash Character

One of the methods to comment out multiple lines in Python is by prepending a hash (#) character to each line. This method is straightforward but might become cumbersome if you have many lines to comment out.

# print("Hello world")
# print("Hello universe")
# print("Hello everyone")
print("Hello campers")

In the code snippet above, the first three print statements are commented out, so only “Hello campers” will be output when the code is run【6†source】.

Using Multi-line String

An alternative and more elegant method to comment out multiple lines in Python is by using a multi-line string enclosed in triple quotes (""" or '''). This method is especially useful when you need to comment out blocks of code.

"""
This is a comment
written in more than just one line
"""
print("Hello, World!")

In this code snippet, a block of text is turned into a multi-line comment, allowing “Hello, World!” to be the only output when the code is run【8†source】【9†source】.

Method	Syntax	Example
Using Hash Character	#	# print("Hello world")
Using Multi-line String	""" or '''	"""This is a comment"""
