In computer club today we started to build a simple text-based calculator that can perform four functions: Add, Subtract, Multiply, and Divide. Students were encouraged to download and install Python if they have not already done so and to work on completing the code we started.

#Computer Club - Simple Python Calculator


def add(a,b):
    return(a+b)

def subtract(a,b):
    return(a-b)


def menu():
    Req=input("Enter A to add, B to Subtract, C to Multiply, D to Divivde")
    return(Req)

def main():
    UserReq=menu()
    if(UserReq=="A"):
        Num1=int(input("Enter the first number: "))
        Num2=int(input("Enter the second number: "))
        ans=add(Num1,Num2)
        print (str(Num1)+" + "+str(Num2)+" = "+str(ans))
    elif (UserReq=="B"):
        #Code to Subtract
        Num1=int(input("Enter the first number: "))
        Num2=int(input("Enter the second number: "))
        ans=subtract(Num1,Num2)
        print (str(Num1)+" - "+str(Num2)+" = "+str(ans))
    elif (UserReq=="C"):
        #Code to Multiply
    elif (UserReq=="D"):
        #Code to Divide
    else:
        print("Response not understood!")

main()
