Question

Say I have the following code in code.py:

from foo import bar
from foo2 import bar2
from foo3 import wrapper

class A(bar):
    def m1(self,x):
        return wrapper(x)

Then I have a reference to an A object in the var “obj” and I get the code for that object like so:

c = inspect.getsource(obj)

which returns:

class A(bar):
    pass

I need to be able to parse “inspect.getsource(obj)” to know that the A class depends on the “from foo import bar” and “from foo3 import wrapper” at the top of the file returned by “inspect.getsourcefile(obj)”.

How can I achieve this?

The only way to get close that I know of is by using modulefinder, but it runs on the whole file and would give me all three imports, not just the one used by the code of interest.

If you want to check if an object or a class inherits from a class in another module, using inspect is probably the wrong way. You can instead use something like that:

for base in A.__bases__:
  print "A depends on module %s" % base.__module__

Or for an object:

for base in (obj.__class__,) + obj.__class__.__bases__:
  print "obj depends on module %s" % base.__module__
