05. Conditions

if, elif, else

Kabhi kabhi code tabhi chalana hai jab condition true ho — if.

marks = 78
if marks >= 90:
    print("Grade A")
elif marks >= 60:
    print("Grade B")
else:
    print("Keep practicing")

Output:

Grade B

Indentation (spaces) Python me zaroori hai — block ke andar 4 spaces.
