How to define global function in Python?

Question

Is there a way to define a function to be global from within a class( or from within another function, as matter of fact)? Something similar to defining a global variable.

Answer 1

You can use global to declare a global function from within a class. The problem with doing that is you can not use it with a class scope so might as well declare it outside the class.

class X:
  global d
  def d():
    print 'I might be defined in a class, but I\'m global'

>> X.d

   Traceback (most recent call last):
   File "", line 1, in 
   AttributeError: 'X' object has no attribute 'd'

>> d()

I might be defined in a class, but I'm global
