  • String Input
  • Integer Input
  • Float Input

4. Python Program to Calculate the Area of a Rectangle

Difficulty: Foundation

Problem Statement

Write a Python program to accept the length and width of a rectangle and calculate its area.

Expected Output

Enter length: 8
Enter width: 5

Area: 40

Python Solution

length = float(input("Enter length: "))
width = float(input("Enter width: "))

area = length * width

print("Area:", area)

Explanation

The program accepts two values and calculates the area using the formula:

Area = Length × Width

  • Arithmetic Operator

5. Python Program to Calculate Simple Interest

Difficulty: Practice

Problem Statement

Accept principal, rate, and time from the user and calculate simple interest.

Expected Output

Enter Principal: 10000
Enter Rate: 8
Enter Time: 2

Simple Interest: 1600.0

Python Solution

principal = float(input("Enter Principal: "))
rate = float(input("Enter Rate: "))
time = float(input("Enter Time: "))

si = (principal * rate * time) / 100

print("Simple Interest:", si)

Explanation

The formula used is:

Simple Interest = (Principal × Rate × Time) / 100

Concepts Covered

  • User Input
  • Formula
  • Arithmetic Operators

6. Python Program to Calculate the Average of Three Numbers

Difficulty: Practice

Problem Statement

Write a Python program to accept three numbers and calculate their average.

Expected Output

Enter second number: 20
Enter third number: 30

Average: 20.0

Python Solution

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

average = (num1 + num2 + num3) / 3

print("Average:", average)

Explanation

The average is calculated by dividing the total sum by the number of values.

Concepts Covered

  • User Input
  • Arithmetic Operators

7. Python Program to Display User Information
