If Statement in Python

In this tutorial, you will learn about if statement and if-else statements in Python along with some examples demonstrating its usage.

Conditional Statements

Conditional statements in python perform operations and check the user-defined conditions constrained to Boolean values and return the resulting value(s) or statements. Python supports the following conditional statements:

• If statement
• If else statement
• Elif statement
• Nested if statement
• Shorthand if and else statement
• Switch case statements

if Statement in Python

The “If statement or simple” if in python is a conditional statement that checks a certain condition and if true it executes the statement inside it. If the condition is false, it jumps out of the loop.

Syntax:

if condition:

            Statements

Example program using if statements 

Input:

[gamipress_button type=”submit”  label=”Run Code Snippet” onclick=”window.open(‘https://coderseditor.com/?id=1215′,’_blank’)”]

a=57
b=57
if a==b:
   print(“ A and B has same values”)

Output:

A and B has same values

So, what if the ‘if’ condition is not met but you need to perform another operation? That’s where the if..else conditional statement comes to the rescue.

If..else statement in Python

The ‘if…else statement’ is a conditional statement that checks a certain condition and if true it executes the statement inside it and if the condition is false, then the statement is else section is executed.

Syntax:

if condition:

            Statements

else:

            Statements

Example problem using the if…else statements 

[gamipress_button type=”submit”  label=”Run Code Snippet” onclick=”window.open(‘https://coderseditor.com/?id=1219′,’_blank’)”]

a=57 
b=75
if a==b: 
    print("A and B has same values") 
else:
     print("A and B does not have the same values")

A and B does not have the same values
