To get this info requires some undocumented Win32 APIs. You could call something like handle.exe from sysinternals which uses them, but I suggest you use the psutil module, available from PyPi. Here is some example code (Py3) I happen to have which lists all the files in use, you should be able to modify that:

import psutil

for proc in psutil.process_iter():
    try:
        flist = proc.get_open_files()
        if flist:
            print(proc.pid,proc.name)
            for nt in flist:
                print("\t",nt.path)

    except psutil.NoSuchProcess as err:
        print("****",err)

Note that there is always a chance of a race condition with these kind of queries - you do not know at what point a process opens or closes a file, or even starts and finishes.

PS: if you are on Python 3, I had some problems installing psutil, but usinging the 2to3 conversion utility on the setup.py fixed the issues.
