如何结束线程任务？

Question

如何结束线程任务？我的代码是这样的：

import threading

def printit():
    threading.Timer(5.0, printit).start()
    print('Hello!')
printit()

Answer 1

试试这个：

def printit(stop):
    thread  = threading.Timer(5.0, printit)
    thread.start()
    print('Hello!')
    x = 'your_stopping_condition'
    if x == 'your_stopping_condition':
        t.cancel()
printit()

Answer 2

import threading

def printit():
    thread  = threading.Timer(1.0, printit)
    thread.start()
    x = 'your_stopping_condition'
    if x == 'your_stopping_condition':
        thread.cancel()
    else:
        print('Hello!')
printit()
