Python Comments

A comment is a part of the coding file that the programmer does not want to execute, rather the programmer uses it to either explain a block of code or to avoid the execution of a specific part of code while testing.

 

Single-Line Comments:

To write a comment just add a ‘#’ at the start of the line.

Example 1:

#This is a 'Single-Line Comment'
print("This is a print statement.")

Output:

This is a print statement. 

 

Example 2:

print("Hello World !!!") #Printing Hello World

Output:

Hello World !!!

 

Example 3:

print("Python Program")
#print("Python Program")

Output:

Python Program

 

 

Multi-Line Comments:

To write multi-line comments you can use ‘#’ at each line or you can use the multiline string.

Example 1: The use of ‘#’.

#It will execute a block of code if a specified condition is true.
#If the codition is false than it will execute another block of code.
p = 7
if (p > 5):
    print("p is greater than 5.")
else:
    print("p is not greater than 5.")

Output:

p is greater than 5.

 

Example 2: The use of multiline string.

"""This is an if-else statement.
It will execute a block of code if a specified condition is true.
If the condition is false then it will execute another block of code."""
p = 7
if (p > 5):
    print("p is greater than 5.")
else:
    print("p is not greater than 5.")

Output:

p is greater than 5.
