First Project - Calculator - georgeziozas - Jan 13, 2015

Sharing the code of my simple (for kids 😏) first program.

I just wrote it and im trying to find better ways to improve the code and to minimize the code lines.

Code 
def choice():

    global a 

    global b

    global r 

    try:

        a = int(input("Give first number "))

        b = int(input("Give second number "))

        action = input("choose + , - , * , / ")

        if action == "+":

            addition()

        elif action == "-":

            substraction()

        elif action == "*":

            multi()

        elif action == "/":

            division()

    except ValueError:

         print ("Give ONLY Number")

         choice()

def substraction():

    r = (a - b)

    print (r)

def addition():

    r = (a + b)

    print (r)

def multi():

    r = (a * b)

    print (r)

def division():

    r = (a / b)

    print (r)

while True:

    choice()

Im guessing this is terminal based? Why not trying using TKinter (Python's built in GUI library) to make it more visually appealing🤝

I am aware of python's libraries :)
But the only reason i created it was to practice on code. nothing else.
Thanks for the advice though 🤝
