(1) What Is Python Comments?
- Comments are descriptions that a programmer writes for a better understanding of the intent and functionality of the program.
- Using comments in programs makes our code more understandable. It makes the program more readable which helps us remember why certain blocks of code were written.
- Other than that, comments can also be used to ignore some code while testing other blocks of code. This offers a simple way to prevent the execution of some lines or write a quick pseudo-code for the program.
They are completely ignored by the Python interpreter.
(2) Single Line Comments
- In Python, we use the hash symbol (#) to write a single-line comment.
- Single-line comments are the short description of the code.
Example-1
# This Is A Single Line Comment
def addition():
sum = 30 + 50
print(sum)
addition()Output: 80Example-2
# This Is A Single Line Comment
def subtraction():
sub = 60 - 25
print(sub)
subtraction()Output: 35(3) Multiple Line Comments
- Python doesn’t offer a separate way to write multiline comments. However, there are other ways to get around this problem.
- We can use (#) at the beginning of each line of comment on multiple lines.
- We can use String Literals (”’ ”’) or (“”” “””) to write multiple-line comments.
Example-1
# It Is A
# Multiline
# Comment
def addition():
sum = 30 + 50
print(sum)
addition()Output: 80Example-2
'''
It IS A
Multiline
Comment
'''
def subtraction():
sub = 60 - 25
print(sub)
subtraction()Output: 35Example-3
"""

def multiplication():
mul = 10 * 10
print(mul)
multiplication()Output: 100
