In Python, comments are used to annotate code with additional information that is not part of the executable program. Comments are ignored by the Python interpreter and are intended for human readers to better understand the code.
Comments in Python start with the hash character (#) and continue until the end of the line. For example:
# This is a comment
print("Hello, World!") # This is another commentIn the above example, the first line is a comment and the second line is a print statement. The third line contains both code and comment.
You can also create multi-line comments in Python by enclosing the text within triple quotes ("""). For example:
"""
This is a multi-line
comment in Python
"""Note that although triple-quoted strings can be used to create multi-line comments, they are not considered to be comments by the Python interpreter and are treated as regular string literals. Therefore, they will be included in the program’s memory usage and may have an impact on performance.
It’s good practice to use comments to explain what your code is doing and why you’re doing it in a certain way. This can help other developers understand your code and make it easier to maintain and modify in the future.
