New submission from John Firestone jo...@freenet.de:
exec(source, Dict()) doesn't call Dict().__getitem__ or Dict().__missing__ if
the source string contains a function and the function references an undefined
global.
class Dict1(dict):
def __getitem__(self, key):
print
John Firestone jo...@freenet.de added the comment:
I find the behavior inconsistent. As you can see from this example, the
exec'uted code *does* call the instance's overloaded __getitem__ and
__missing__ methods when outside a function, but doesn't when inside
John Firestone jo...@freenet.de added the comment:
Thank you all for the quick and interesting responses!
Here is another example, this time showing a simple
s
sometimes behaves like
globals()['s']
and sometimes doesn't.
class Dict(dict):
def __getitem__(self, key):
if key
