在前面先定义myThread类

import threading

class myThread(threading.Thread):
    def __init__(self, command):
        threading.Thread.__init__(self)
        self.cmd = command

    def run(self):
        print"Starting" + self.cmd
        os.system(self.cmd)
        print"Exiting" + self.cmd

使用：

thread1 = myThread('python daily_report_GUI.py')
# thread2 = ...
thread1.start()
# thread2.start()
