Question: If I have a Python class, and would like to call a function from it depending on a variable, how would I do so? I imagined following could do it:

```
class CallMe: # Class

   def App(): # Method one

      ...

   def Foo(): # Method two

      ...

variable = "App" # Method to call

CallMe.variable() # Calling App()

```

But it couldn't. Any other way to do this?

Answer: 
Your class has been declared as an "old-style class". I recommend you make all your classes be "new-style classes".

The difference between the old and the new is that new-style classes can use inheritance, which you might not need right away. But it's a good habit to get into.

Here is all you have to do to make a new-style class: you use the Python syntax to say that it inherits from "object". You do that by putting parentheses after the class name and putting the name *object* inside the parentheses. Like so:

```
class CallMe(object): # Class

   def App(): # Method one

      ...

   def Foo(): # Method two

      ...

```

As I said, you might not need to use inheritance right away, but this is a good habit to get into. There are several questions here on StackOverflow to the effect of "I'm trying to do *X* and it doesn't work" and it turns out the person had coded an old-style class.
Your code does not look like python, may be you want to do like this?

```
class CallMe:

    def App(self): #// Method one
        print "hello"

    def Foo(self): #// Method two
        return None

    variable = App #// Method to call

CallMe().variable() #// Calling App()

```
