Function attributes again

[Fernando Rodríguez]

Hi!

	How can I check (from within a function) if it has attributes?  I
tried if __dict__ == None in the definition, but it doesn't work:

def f(a, b):
	z = 0
	if __dict__ == None:
		__dict__['c'] = 4
	
	return z + a + b

>>> f(8,3)
Traceback (most recent call last):
  File "<pyshell#39>", line 1, in ?
    f(8,3)
  File "<pyshell#28>", line 3, in f
    if __dict__ == None:
NameError: global name '__dict__' is not defined

What's going on? O:-)
