Comments in Python

 In Python, comments are used to explain the code or to make it more readable. Comments are ignored by the interpreter and are not executed. They start with the "#" symbol and continue until the end of the line.

For example:

# This is a single line comment 

It is a good practice to add comments to your code, especially in large or complex projects, to make it easier for others (or yourself) to understand what the code is doing.

In addition to the regular comments, Python also supports inline comments, which can be used to comment out a single line of code. They are created by adding the "#" symbol at the beginning of the line of code that needs to be commented out.

Example:

x = 5  # inline comment 

Python also support docstrings which are used to provide documentation for a module, class, or function. Docstrings are enclosed in triple quotes (""") and are typically placed immediately after the definition of the module, class, or function.

Example:

def add(a, b): 
    """
    This function adds two numbers
    """ 
    return a + b

In summary comments are useful to explain what your code is doing, making it more readable and easier to understand for others. Python supports single line comments, multi-line comments, inline comments and docstrings which are specific type of comments used to provide documentation.
