Suppose I have a function that needs access to globals:

As written, spam() only sees its own globals, i.e. those of the
module in
which spam is defined. But I want spam to see the globals of the caller.
# module B
import A
A.spam() # I want spam to see globals from B
I can have the caller explicitly pass the globals itself:
def spam(globs=None):
if globs is None:
globs = globals()
introspect(globs)
But since spam is supposed to introspect as much information as
possible,
I don't really want to do that. What (if anything) are my other options?
How about this?
# module A.py
import inspect
def spam():
return inspect.stack()[1][0].f_globals
In Python 3, the attribute is __globals__.
Er... no it isn't? Sorry if I'm mistaken but I believe you're thinking
of the attribute formerly known as func_globals. But in the above
inspect.stack()[1][0] is not a function, it's a frame object. In fact
it's the same thing as sys._getframe().f_back, I think.
