In Python, comments are lines of code that are not executed by the interpreter. They are used to explain what a piece of code does or to provide additional information about it.
There are two types of comments in Python: single-line comments and multi-line comments.
Single-line comments start with the
# symbol and extend to the end of the line. For example:
# This is a single-line comment
Multi-line comments start with the
""" symbol and extend to the next
""" symbol. They can span multiple lines and are often used to provide a detailed explanation of a block of code. For example:
""" This is a multi-line comment. It can span multiple lines and is often used to provide a detailed explanation of a block of code. """
It is a good practice to include comments in your code to make it easier to understand and maintain. It is especially useful when you are working on a team or when you revisit your code after a long time.
Here is an example of how comments can be used in a Python program:
# This program calculates the area of a rectangle # Define the length and width of the rectangle length = 5 width = 10 # Calculate the area of the rectangle area = length * width # Print the result print("The area of the rectangle is", area) """ This block of code calculates the area of a rectangle using its length and width. The result is printed to the screen. """
