The second import actually doesn't happen. You need to reload it. This can be tested by putting print('loading threading') in threading.py.

Your first method-thread will still think it's main thread. So no idea if this is a bug or wrong use. 'import threading' should be one of the first lines in your main code/thread?


import _thread
import time
import importlib
barrier = 0

def method():
    import threading  # Will make threading the wrong thread.
    global barrier
    print(threading.main_thread())
    print(threading.current_thread())
    barrier = 1

_thread.start_new_thread(method, ())

while barrier != 1:
    time.sleep(.1)

import threading
importlib.reload(threading)
print(threading.main_thread())
print(threading.current_thread())
