如果要在多个线程中使用win32com，则需要做更多的工作，因为
COMObject不能直接传递给线程。您需要在线程之间使用
CoMarshalInterThreadInterfaceInStream()和
CoGetInterfaceAndReleaseStream()传递实例：
import pythoncom, win32com.client, threading, timedef start(): # Initialize pythoncom.CoInitialize() # Get instance xl = win32com.client.Dispatch('Excel.Application') # Create id xl_id = pythoncom.CoMarshalInterThreadInterfaceInStream(pythoncom.IID_IDispatch, xl) # Pass the id to the new thread thread = threading.Thread(target=run_in_thread, kwargs={'xl_id': xl_id}) thread.start() # Wait for child to finish thread.join()def run_in_thread(xl_id): # Initialize pythoncom.CoInitialize() # Get instance from the id xl = win32com.client.Dispatch( pythoncom.CoGetInterfaceAndReleaseStream(xl_id, pythoncom.IID_IDispatch) ) time.sleep(5)if __name__ == '__main__': start()有关更多信息，请参见：https : //mail.python.org/pipermail/python-
