Comments in Python are used to explain and document the code. They are ignored by the interpreter and do not affect the execution of the program. In Python, there are two types of comments: single-line comments and multi-line comments.
- Single-line comments: Single-line comments begin with a hash symbol (#) and continue until the end of the line. They are used to document a single line of code or to provide context for the code.
Example:
# This is a single-line comment in Python x = 5 # This is another single-line comment

- Single-line comments: Single-line comments begin with a hash symbol (#) and continue until the end of the line. They are used to document a single line of code or to provide context for the code.
Example:
# This is a single-line comment in Python
x = 5 # This is another single-line comment
- Multi-line comments: Multi-line comments, also called block comments, are used to document longer sections of code or to provide more detailed explanations. In Python, multi-line comments are created by enclosing the comment in triple quotes (”’ comment ”’).
Example:
''' This is a multi-line comment in Python. It can be used to document longer sections of code or to provide more detailed explanations. ''' x = 5 # This is a single-line comment
It is good practice to use comments in your code to make it more readable and understandable for other developers who may need to maintain or modify the code in the future.
Python Docstring:
Python docstrings are a way to document modules, classes, functions, and methods in Python. They are similar to comments, but they provide more structured and comprehensive documentation.
A docstring is a string literal that appears as the first statement in a module, function, class, or method definition. It can span multiple lines and can include rich text formatting, such as bold or italic text.
Docstrings can be accessed at runtime using the __doc__ attribute of the module, class, function, or method. They can also be used by automated tools, such as the built-in help() function, to generate documentation for a program or module.
Here is an example of a docstring for a function:
def greet(name):
"""
This function takes a name as input and returns a greeting message.
Parameters:
name (str): The name of the person to greet.
Returns:
str: A greeting message that includes the person's name.
"""
return f"Hello, {name}! How are you doing?"
In this example, the docstring explains the purpose of the function, the parameters it accepts, and the value it returns. It also includes the type of the parameter name.
It is good practice to include docstrings in your code to make it more understandable and maintainable.
