If Statements Examples- Python VII

Interactive Python Activities

Example 1: Grading System

Write a Python program to calculate the grade of a student based on their marks. The program should prompt the user to input a numerical grade (0–100) and determine the letter grade using the following ranges:

• 90–100: Grade A
• 80–89: Grade B
• 70–79: Grade C
• 60–69: Grade D
• Below 60: Grade F

marks = 85
if marks >= 90:
 print("Grade: A")
elif marks >= 80:
 print("Grade: B")
elif marks >= 70:
 print("Grade: C")
elif marks >= 60:
 print("Grade: D")
else:
 print("Grade: F")

Enter Marks (0-100):

Hint: Use conditional statements to evaluate different ranges of marks.

Example 2: Calculating Discounts

Write a Python program to calculate the final price of an item after applying a discount. The program should use the following discount rules:

• 10% discount if the amount is greater than $1000
• 5% discount if the amount is greater than $500 but less than or equal to $1000
• No discount if the amount is $500 or less

amount = 150
if amount > 1000:
 discount = amount * 0.1
elif amount > 500:
 discount = amount * 0.05
else:
 discount = 0
print(f"Total discount: {discount}")

Enter Amount:

Hint: Check the amount against different thresholds and apply the corresponding discount.

Example 3: Checking Eligibility to Vote

Write a Python program to determine whether a person is eligible to vote. The program should ask the user to input their age and check if it meets the minimum voting age requirement (18 years or older).

age = 20
if age >= 18:
 print("Eligible to vote")
else:
 print("Not eligible to vote")

Enter Age:

Hint: Use a simple condition to check if age is greater than or equal to 18.
