Is it possible to get “importing module” in “imported module” in Python?

Question

For imported module, is it possible to get the importing module (name)? I\'m wondering if inspect can achieve it or not~

Answer 1

It sounds like you solved your own problem: use the inspect module. I'd traverse up the stack until I found a frame where the current function was not __import__. But I bet if you told people why you want to do this, they'd tell you not to.

Answer 2

import inspect
result = filter(lambda v:inspect.ismodule(v), globals().values())
#result is a collection of all imported modules in the file, the name of any of which can be easily got by .__name__
#replace globals() with inspect.getmembers(wanted_module) if you want the result outside the wanted module

Answer 3

foo.py:

import bar

---

bar.py:

import traceback
try:
    filename,line_number,function_name,text = traceback.extract_stack()[-2]
    print(filename,line_number,function_name,text)
except IndexError:
    pass

---

Running foo.py yields something like

('/home/unutbu/pybin/foo.py', 4, '<module>', 'import bar')

Answer 4

Even if you got it to work, this is probably less useful than you think since subsequent imports only copy the existing reference instead of executing the module again.
