Here’s an example of why mborch’s statement is true:

 class A:
 def __init__(self, value=0):
 self.b = value
 def __str__(self):
 if self.b == 0:
 global a
 a = A(1)
 elif self.b == 1:
 import __builtin__, __main__
 __builtin__.a = 2
 del __main__.a
 return str(self.b)
 a = A()
 
 def foo():
 print a
 print a
 print a
 
 foo()

This generates:

 1
 2
 3

but it’s a different ‘a’ in all three cases; the last isn’t even from the module’s namespace.
