Concepts Covered

  • Comparison operators
  • if…else

5. Python Program to Find the Largest of Three Numbers

Difficulty: Practice

Problem Statement

Write a Python program to find the largest among three numbers using if...elif...else.

Python Solution

num1 = int(input("Enter first number: "))
num2 = int(input("Enter second number: "))
num3 = int(input("Enter third number: "))

if num1 >= num2 and num1 >= num3:
    print("Largest Number:", num1)
elif num2 >= num1 and num2 >= num3:
    print("Largest Number:", num2)
else:
    print("Largest Number:", num3)

Sample Output

Enter first number: 45
Enter second number: 18
Enter third number: 30
Largest Number: 45

Explanation

The program compares all three numbers and prints the largest one.

Concepts Covered

  • Logical operators

6. Python Program to Check Whether a Year is a Leap Year

Difficulty: Practice

Problem Statement

Write a Python program to check whether a given year is a leap year.

Python Solution

year = int(input("Enter a year: "))

if (year % 400 == 0) or (year % 4 == 0 and year % 100 != 0):
    print("Leap Year")
else:
    print("Not a Leap Year")

Sample Output

Enter a year: 2024
Leap Year

Explanation

A leap year is divisible by 400 or divisible by 4 but not by 100.

Concepts Covered

  • Nested conditions
  • Logical operators

7. Python Program to Calculate Grade Based on Marks

Difficulty: Practice

Problem Statement

Write a Python program to display the grade based on the following criteria:

  • 90 and above → A
  • 75–89 → B
  • 60–74 → C
  • 40–59 → D
  • Below 40 → Fail

Python Solution

marks = int(input("Enter marks: "))

if marks >= 90:
    print("Grade A")
elif marks >= 75:
    print("Grade B")
elif marks >= 60:
    print("Grade C")
elif marks >= 40:
    print("Grade D")
else:
    print("Fail")

Sample Output

Enter marks: 82
Grade B

Explanation

if...elif...else helps check multiple conditions in sequence.

Concepts Covered

  • Multiple conditions
  • if…elif…else

8. Python Program to Check Whether a Character is a Vowel or Consonant

Difficulty: Practice

Problem Statement

Write a Python program to check whether a character entered by the user is a vowel or a consonant.

Python Solution

character = input("Enter a character: ").lower()

if character in "aeiou":
    print("Vowel")
else:
    print("Consonant")

Sample Output

Enter a character: a
Vowel

Explanation

The in operator checks whether the character exists in the string "aeiou".

Concepts Covered

  • if…else
  • Membership operator
