prime number program in python

 Here is a sample Python program that checks if a given number is a prime number:


python

Copy code

def is_prime(n):

    if n <= 1:

        return False

    for i in range(2, int(n**(1/2))+1):

        if n % i == 0:

            return False

    return True


num = int(input("Enter a number: "))

if is_prime(num):

    print(num, "is a prime number.")

else:

    print(num, "is not a prime number.")

This program takes an input from the user, and checks if that number is prime by dividing it by all integers greater than 1 and less than the square root of that number, if the number is divisible by any of the integers it returns not a prime number otherwise it returns prime number.

fibonacci series in python

Here is an example of a code for generating the Fibonacci series in Python: Python def fibonacci_series(n):     if n <= 0:         return []     elif n == 1:         return [0]     elif n == 2:         return [0, 1]     else:         fib_list = [0, 1]         for i in range(2, n):             fib_list.append(fib_list[i-1] + fib_list[i-2])         return fib_list n = int(input("Enter the number of terms for Fibonacci series: ")) print(fibonacci_series(n)) The function fibonacci_series(n) takes in an integer n as input and returns a list of the first n terms of the Fibonacci series. The function first checks if the input is less than or equal to 0, in which case it returns an empty list. If the input is 1, it returns a list with a single element of 0. If the input is 2, it returns a list with 2 elem...

python code for calculator

 Here is an example of a simple calculator program written in Python: Python Copy code def add(x, y):     return x + y def subtract(x, y):     return x - y def multiply(x, y):     return x * y def divide(x, y):     return x / y print("Select operation.") print("1.Add") print("2.Subtract") print("3.Multiply") print("4.Divide") choice = input("Enter choice(1/2/3/4): ") num1 = float(input("Enter first number: ")) num2 = float(input("Enter second number: ")) if choice == '1':     print(num1, "+", num2, "=", add(num1, num2)) elif choice == '2':     print(num1, "-", num2, "=", subtract(num1, num2)) elif choice == '3':     print(num1, "*", num2, "=", multiply(num1, num2)) elif choice == '4':     print(num1, "/", num2, "=", divide(num1, num2)) else:     print("Invalid Input") This program allows...
