Python Comments

Python comments

Created By: chatGPT

Comments in Python are essential for explaining and documenting your code. They help others (and yourself) to understand what the code does. There are two main types of comments in Python: single-line comments and multi-line comments.

# This is a single-line comment
print('Hello, World!')

To create a single-line comment, simply use the hash symbol (#) at the beginning of the line. Anything following the hash symbol on that line will be considered a comment and will be ignored by the Python interpreter.

# This is a single-line comment

For multi-line comments, you can use triple quotes (''' or ") to enclose the comment. Although this is technically a string that is not assigned to a variable, Python will treat it as a comment if it's not part of an expression or assigned value.

''' 
This is a multi-line comment.
It spans multiple lines.
'''

Using comments effectively can make your code more readable and maintainable. It's a good practice to add comments that explain complex code, summarize what a section of your code does, or note any important considerations.

def calculate_area(radius):
    # Function to calculate the area of a circle
    area = 3.14 * (radius ** 2)
    return area

Lastly, remember to keep your comments clear and concise. Avoid stating the obvious; for instance, comments such as # This adds two numbers can be redundant if the code is self-explanatory.

# Instead of this:
result = a + b  # This adds a and b

# You can simply write:
result = a + b  # Adding two variables
