Solutions

  1. Input marks in 3 subjects and find the total and percentage.

    Show Code
    marks1 = int(input("Enter marks for subject 1: "))
    marks2 = int(input("Enter marks for subject 2: "))
    marks3 = int(input("Enter marks for subject 3: "))
    total = marks1 + marks2 + marks3
    percentage = (total / 300) * 100
    print("Total Marks:", total)
    print("Percentage:", percentage)
  2. Input name, hobby, and age, then print them as a paragraph.

    Show Code
    name = input("Enter your name: ")
    hobby = input("Enter your hobby: ")
    age = input("Enter your age: ")
    print("Hi, my name is", name + ".", "I am", age, "years old and I love", hobby + ".")
  3. Take a string and repeat it n times (using *).

    Show Code
    text = input("Enter a string: ")
    n = int(input("How many times to repeat? "))
    print(text * n)
  4. Input two numbers and swap their values using a temporary variable.

    Show Code
    num1 = input("Enter the first number: ")
    num2 = input("Enter the second number: ")
    temp = num1
    num1 = num2
    num2 = temp
    print("After swapping: First number =", num1, "Second number =", num2)
