I'm trying to import a module so that the globals() of the importer
module are available to the imported module itself. Consider the
following scenario:
=== mymod.py ===
def go():
some_special_function(1,2)
# 'some_special_function' is a built-in function available in the
scope of foo.py (see below)
=== foo.py ===
some_special_function(3,4) # 'some_special_function' is a built-in
function
import mymod
mymod.go()
=== EOF ===
The problem is this: in foo.py, you can call 'some_special_function'
all you want, because it's builtin. You can even 'print globals()' to
verify that it is available.
However, when mymod.py tries to invoke 'some_special_function', it
fails because the function is NOT available in that scope.
So, the question is: how can I make builtin functions available in the
test.py scope available to the mymod.py scope?
One awkward solution is to deliberately initialize mymod.py ilke so:
=== mymod.py ===
globs=None
def initialize(globs_): globs = globs_
def go():
globs['some_special_function'] (1,2)
=== foo.py ===
some_special_function(3,4) # 'some_special_function' is a built-in
function
import mymod
mymod.initialize(globals())
mymod.go()
=== EOF ===
That will work, but it's a bit ugly. Plus, I have to repeat it for
every module with the same problem (of which I have many!).
Is there a way to use __import__ to make this work? Any ideas?
Thanks,

Your sample is very hard to follow, because you're mis-using the word
built-in. Built-ins are part of the Python implementation, and
available everywhere, while you apparently just mean a function visible
in foo.py, which may have been imported from somewhere else.
One solution would be that after importing mymod, you assign to its
global space, as follows:
def some_special_function():
.....
import mymod
mymod.some_special_function = some_special_function
You're adding a global name to the mymod namespace, and giving it a
reference to a function in your own space.
Note that the two names don't have to be the same in the two files. You
could use, for example:
import os
mymod.some_special_function = os.path.join
