从一个python文件获取本地函数列表到另一个python文件

Question

I have a requirement where I need to parse the functions defined in a python file from another python file.

eg I have a python file with following contents:

a.py

import os, sys

def function1('text'):
   pass
def function2('text'):
   pass

Another file is: b.py

interested_func = 'function2'

function_list = <code to fetch the functions defined in a.py>
if interested_func in function_list:
   print 'match found'

How can I get the functions from a.py into b.py so that I can compare the same with the 'interested_func' data and can do specific task based on the match.

Please note that I have 100s of files with different functions defined inside them, so I do not want to import the file.

Please help, thanks in advance!

You should probably use the importlib module:

import importlib

obj = importlib.import_module(module)
print(dir(obj))

You can read more about importlib over in the Python docs .

If that doesn't work for you, then you'll probably want to look at some static code analysis tools such as pylint that might give you a clue into how to do this sort of thing. Another place to look would be to check out PyDev's source code and see how it does code analysis.
