Python Program to Make a Simple Calculator 

Example: Code Program

#This Function Add Two Number
def add(a, b):

    return a+b

#This Function Subtract 2nd Number to 1st

def sub(a, b):

    return a - b

#This Function Multiply Two Number

def mul(a, b):

    return a*b

#This Function Divide 1st Number in 2nd

def div(a, b):

    return int(a/b)

#This Function show Remainder

def mod(a, b):

    return int(a%b)

print("Plz Enter any Option")

print("1-addition")

print("2-Subtraction")

print("3-Multiplication")

print("4-Divide")

print("5-Remainder")

print("------------------------")

while True:

    op = input("Enter Any Option:")

    print("------------------------")

    if("User Enter 1, 2,3,4"):

        x = int(input("Enter First Number:"))

        y = int(input("Enter Second Number:"))

        if op == '1':

            print(x, "+", y ,"=",add(x,y))

        elif op == '2':

            print(x, "-" ,y, "=",sub(x,y))

        elif op == '3':

            print(x, "*" ,y, "=",mul(x,y))

        elif op == '4':

            print(x, "/" ,y, "=",div(x,y))

        elif op == '5':

            print(x, "%" ,y, "=",mod(x,y))

        break

    else:

        print("Invalid Option")
