I have some code for a calculator, and I was wondering what I could look at to make the code smaller, easier to read or better in any way. I'm particularly looking at my global variable x. Is there any way to change the code to completely remove that? Someone mentioned a getTwoInputs() function, but with multiple different questions (powers() input and addition() input) I assume it would take up the same space.def Addition():    print('Addition: What are your numbers?')    a = float(input('First Number:'))    b = float(input('Second Number:'))    print('Your Answer is:', a + b)def Subtraction():    print('Subtraction: What are your numbers?')    c = float(input('First Number:'))    d = float(input('Second Number:'))    print('Your Answer is:', c - d)def Multiplication():    print('Multiplication: What are your numbers?')    e = float(input('First Number:'))    f = float(input('Second Number:'))    print('Your Answer is:', e * f)def Division():    print('Division: What are your numbers?')    g = float(input('First Number:'))    h = float(input('Second Number:'))    print('Your Answer is:', g / h)def Roots():    print('Roots: What do you want to Root?')    i = float(input('Number:'))    print('Roots: By what root?')    j = float(input('Number:'))    k = ( 1 / j )    print('Your Answer is:',i**k)def Powers():    print('Powers: What number would you like to multiply by itself?')    l = float(input('Number:'))    print('Powers: How many times would you like to multiply by itself?')    m = float(input('Number:'))    print('Your Answer is:',l**m)x = 'test'def Question():        print('What would you like to do?')        x = input('(Add, Subtract, Divide, Multiply, Powers, Roots or Quit)')        if x.lower().startswith('a'):            x = 'test123'            print(Addition())            x = 'test'        elif x.lower().startswith('d'):            x = 'test123'            print(Division())            x = 'test'        elif x.lower().startswith('m'):            x = 'test123'            print(Multiplication())            x = 'test'        elif x.lower().startswith('s'):            x = 'test123'            print(Subtraction())            x = 'test'        elif x.lower().startswith('r'):            x = 'test123'            print(Roots())            x = 'test'        elif x.lower().startswith('p'):            x = 'test123'            print(Powers())            x = 'test'        elif x.lower().startswith('e'):            x = 'test'            print(exit())        elif x.lower().startswith('q'):            x = 'test'            print(exit())        else:            print(Please type the first letter of what you want to do.)            print(Question())while x == 'test':    Question()
