global statement and scoping

[jochen.stier]

Hi everyone,


I am compiling the following script using Py_CompileString


def compute(node):
#global compute

iter = node.getChild(0)
while iter:
if isinstance(iter, Group):
compute(iter)
print iter
iter = iter.next

compute(self.a0)


The I evaluate the script using PyEval_EvalCode and get a ''global name
"compute" is not
defined' error at the line of the recursive call. When I comment in the
"global" statement at the beginning of the function then everything
works fine. What's strange is the once I comment out the statement
again it still works... Somewhere something is written into a
dictionary in dunno where ?

Is it normal to have the global statement at the beginning of a
function like that ?

Cheers
Jochen
