python calculator library code example

Example 1: python calculator

print("Enter Your Choice 1(Add)/2(Sub)/3(Divide)/4(Multiply)")
num = int(input())
if num == 1:
    print("Enter Number 1 : ")
    add1  = int(input())
    print("Enter Number 2 : ")
    add2 = int(input())
    sum = add1 + add2
    print("The Sum Is ", sum)
elif num == 2:
    print("Enter Number 1 : ")
    sub1  = int(input())
    print("Enter Number 2 : ")
    sub2 = int(input())
    difference = sub1 - sub2
    print("The Difference Is ", difference)
elif num == 3:
    print("Enter Number 1 : ")
    div1  = float(input())
    print("Enter Number 2 : ")
    div2 = float(input())
    division = div1 / div2
    print("The Division Is ", division)
elif num == 4:
    print("Enter Number 1 : ")
    mul1 = int(input())
    print("Enter Number 2 : ")
    mul2 = int(input())
    multiply = mul1 * mul2
    print("The Difference Is ", multiply)
else:
    print("enter a valid Number")

Example 2: calculator python

#this is a fraction calculator
def fractions_regular(fractions):
    f1 = input(13,25)
    f1 = fractions.Fraction(f1)
    f2 = input(6,25)
    f2 = fractions.Fraction(f2)
    operation = input('what is your iperation?')
    if operation == '+':
        print('{} + {} = {}'.format(f1, f2, f1 + f2))
    if operation == "-":
        print('{} - {} = {}'.format(f1, f2, f1 - f2))
    if operation == "*":
        print('{} * {} = {}'.format(f1, f2, f1 * f2))
    if operation == "/":
        print('{} / {} = {}'.format(f1, f2, f1 / f2))
