here is my code for a calculator:
def menu():
print "Welcome to calculator.py" print "your options are:" print " "
print "1) Addition" print "2) Subtraction" print "3) Multiplication"
print "4) Division" print "5) Quit calculator.py" print " " return
input ("Choose your option: ")
def add(a,b): print a, "+", b, "=", a + b
def sub(a,b): print b, "-", a, "=", b - a
def mul(a,b): print a, "*", b, "=", a * b
def div(a,b): print a, "/", b, "=", a / b def main(): loop = 1
choice = 0 while loop == 1: choice = menu() if choice == 1:
add(input("Add this: "),input("to this: ")) elif choice == 2:
sub(input("Subtract this: "),input("from this: ")) elif choice
== 3: mul(input("Multiply this: "),input("by this: ")) elif
choice == 4: div(input("Divide this: "),input("by this: "))
elif choice == 5: loop = 0
print "Thank you for using calculator.py!"
main()
Few questions:
why do i have to press enter for it to initialisewhy does it print the stuff in
menu() again after doing the equationi am trying to understand classes if
anyone has time to make all these functions go into a class calculator and have
it still work and send me the code so i can have an example to refer to that
would be great
