Conditional Statements in Python

Conditional statements allow a program to execute different blocks of code based on certain conditions. These statements control the flow of execution based on conditions evaluated as True or False.

1. if Statement

The if statement executes a block of code if the given condition is True.

main.py

age = 18
if age >= 18:
    print("You are eligible to vote.")

2. if-else Statement

The if-else statement provides an alternative block of code to execute when the condition is False.

main.py

num = 10
if num % 2 == 0:
    print("Even number")
else:
    print("Odd number")

3. if-elif-else Statement

The if-elif-else statement checks multiple conditions and executes the first one that is True.

main.py

score = 85
if score >= 90:
    print("Grade: A")
elif score >= 80:
    print("Grade: B")
elif score >= 70:
    print("Grade: C")
else:
    print("Grade: F")

4. Nested if Statement

An if statement inside another if statement is called a nested if.

main.py

x = 15
if x > 10:
    print("Greater than 10")
    if x > 20:
        print("Also greater than 20")
    else:
        print("But not greater than 20")

Conclusion

Conditional statements are essential for decision-making in Python. They allow a program to execute different code based on specific conditions, making the program dynamic and responsive.
