Python: How To Use Named Variables From One Function In Other Functions

I'm a newbie programmer trying to make a program, using Python 3.3.2, that has a main() function which calls function1(), then loops function2() and function3(). My code generally

Solution 1:

Don't try to define it a global variable, return it instead:

def function2():
    name = input("Enter name: ")
    return name

def function3():
    print(function2())

---

If you want to use variables defined in function to be available across all functions then use a class:

class A(object):

   def function1(self):
       print("hello")

   def function2(self):
       self.name = input("Enter name: ")

   def function3():
       print(self.name)

   def main(self):  
       self.function1()
       while True:
          funtion2()
          function3()
          if not self.name:
              break

A().main()

Solution 2:

Define the variable outside of your functions, and then declare it first as global inside with the global keyword. Although, this is almost always a bad idea because of all of the horrendous bugs you'll end up creating with global state.
