Python Comments
Python Comments
In Python, comments are used to add explanations or notes within the code. Comments are ignored by the Python interpreter and are not executed as part of the program. They are helpful for documenting code, providing context, or temporarily excluding code from execution during testing or debugging.
1. Single-line Comments:
Single-line comments start with the #
symbol and continue until the end of the line. Anything after the #
symbol on that line is treated as a comment.
# This is a single-line comment
print("Hello, World!") # This is also a comment
2. Multi-line Comments:
Python does not have a specific syntax for multi-line comments like some other programming languages. However, developers often use triple-quotes ('''
or """
) to create multi-line strings as a way to write multi-line comments. Since these strings are not assigned to any variable, they act as comments and are ignored by the interpreter.
'''
This is a multi-line comment.
It spans multiple lines.
'''
print("Hello, World!")
Or by using triple double-quotes:
"""
Another way to create a multi-line comment.
It's enclosed in triple double-quotes.
"""
print("Hello, World!")
While the triple-quotes approach works for multi-line comments, it's worth noting that it creates string literals, and if not assigned to a variable or used in any way, it serves the purpose of a comment.
Remember that writing clear and concise comments can significantly improve the readability and maintainability of your code. It's good practice to provide comments that explain complex logic, functions, or any parts of the code that might be unclear to others (or to yourself in the future).
