# Simple Calculator

num1 = float(input("Enter the first number: ")) num2 = float(input("Enter the second number: ")) sum = num1 + num2 print("Sum:", sum) difference = num1 - num2 print("Difference:", difference) product = num1 * num2 print("Product:", product) quotient = num1 / num2 print("Quotient:", quotient)

This program prompts the user to enter two numbers and performs basic arithmetic operations like addition, subtraction, multiplication, and division.

# Guessing Game

import random number = random.randint(1, 10) guess = int(input("Guess a number between 1 and 10: ")) if guess == number:    print("Congratulations! You guessed it right.") else:    print("Sorry, wrong guess. The number was", number)

In this program, the computer generates a random number between 1 and 10, and the user tries to guess the number. It provides feedback on whether the guess was correct or not.

## Check Prime Number

num = int(input("Enter a number: ")) if num > 1:    for i in range(2, num):        if num % i == 0:            print(num, "is not a prime number.")            break    else:        print(num, "is a prime number.") else:    print(num, "is not a prime number.")

This program checks if a given number is prime or not. It uses a simple loop to iterate through numbers and checks for divisibility.

## Fibonacci Series

n = int(input("Enter the number of terms: ")) a, b = 0, 1 print("Fibonacci Series:") print(a, end=" ") for _ in range(n - 1):    print(b, end=" ")    a, b = b, a + b

This program generates the Fibonacci series up to a specified number of terms. It uses a loop and two variables to calculate and display the series.
