How to implement if-else conditions in python code?

Question

Anubhav Kumar · Accepted Answer

In Python, you use if–elif–else statements for conditional branching.
Basic Syntax
if condition1:
    # block of code if condition1 is True
elif condition2:
    # block of code if condition2 is True
else:
    # block of code if none of the above are True
if → checks the first condition.elif (else-if) → checks more conditions if the previous ones failed.else → runs if no condition is True.
Example 1: Simple If-Else
age = 18
if age andgt;= 18:
    print("You are an adult.")
else:
    print("You are a minor.")
Example 2: If-Elif-Else Chain
marks = 72
if marks andgt;= 90:
    print("Grade: A")
elif marks andgt;= 75:
    print("Grade: B")
elif marks andgt;= 60:
    print("Grade: C")
else:
    print("Grade: D")
Example 3: Nested If
num = 15
if num andgt; 0:
    if num % 2 == 0:
        print("Positive even number")
    else:
        print("Positive odd number")
else:
    print("Negative number or zero")
Example 4: One-line If (Ternary Operator)
x = 10
result = "Even" if x % 2 == 0 else "Odd"
print(result)  # Output: Even
Summary:
Use if when you want to check a condition.Use elif when you need multiple conditions.Use else as a fallback when no condition matches.
