if else elif in Python

Take care of indenting as you will get error. The code to be executed within if condition is to be indented to create a block of code.
x=10
y=20
if(x>y):
    print("x is greater than y")
else:
    print("y is greater than x")
Output is here
y is greater than x

Using elif

If the first if condition check fails then we can go for for one more check by using elif before using else.
if elif else condition check
x=10
y=20
if(x>y):
    print("x is greaeter than y")
elif(y>15):
    print("y is greater than 15")
    
else:
    print("y is greater than x but less than 15")
Output is here
y is greater than 15

What is the difference between else and elif ?

We don’t check any condition while using else, the code within else block is always executed once the (previous) if condition fails. In case of elif , one more condition is checked.
