Solutions

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)

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 + ".")

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)

Input two numbers and print them separated by a custom separator.

Show Code

num1 = input("Enter the first number: ")
num2 = input("Enter the second number: ")
separator = input("Enter a custom separator: ")
print(num1, num2, sep=separator)

Print a message on one line and another message on the same line using the end argument.
Show Code
print("This is the first message.", end=" ") print("This is the second message.")

Input marks in two subjects and calculate their average.

Show Code

marks1 = int(input("Enter marks for subject 1: "))
marks2 = int(input("Enter marks for subject 2: "))
average = (marks1 + marks2) / 2
print("Average Marks:", average)

Input the length and breadth of a rectangle and calculate its area.

Show Code

length = float(input("Enter the length of the rectangle: "))
breadth = float(input("Enter the breadth of the rectangle: "))
area = length * breadth
print("Area of the rectangle:", area)

Input the cost of an item and the quantity purchased, then calculate the total cost.

Show Code

cost = float(input("Enter the cost of one item: "))
quantity = int(input("Enter the quantity purchased: "))
total_cost = cost * quantity
print("Total Cost:", total_cost)

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)

Input the base and height of a triangle and calculate its area.

Show Code

base = float(input("Enter the base of the triangle: "))
height = float(input("Enter the height of the triangle: "))
area = 0.5 * base * height
print("Area of the triangle:", area)
