How to Comment a Single Line in Python?

To comment a single line in Python, you can use the # (hash) character. Anything following the # on the same line is treated as a comment and is ignored by the Python interpreter. Here’s an example:

# This is a comment
print("Hello, world!")  # This is another comment

In this example, the first line starting with # is a comment. It serves as a helpful explanation or description of the code that follows. The second line demonstrates how you can add a comment at the end of a line after the code.

Comments are useful for adding notes, clarifications, or explanations to your code. They are ignored during the execution of the program and are only meant to provide information for human readers.

Remember that comments are an essential practice in programming as they improve code readability and understanding, especially for others who may review or maintain the code in the future.
