Atexit没有在python中注册

Posted 2021-04-12

事实证明问题不同现在我在Tkinter中有一个循环：

def main():
    #Global Variables
    windows = []
    buttons = []
    labels = []
    messageboxes = []
    global theme
    theme = 0
    listboxes = []
    global register
    register = []
    global path
    path = ""
    # Lotsa' Code
    Tkinter.mainloop()

if __name__ == "__main__":
    main()

def save_f():
    global register
    outFile = open('FobbySave.txt', 'wb')
    pickle.dump(register, outFile)
    outFile.close()
global register     
#At Quit
atexit.register(save_f)

atexit失败了。但是当我尝试打印寄存器时，它没有任何问题。当我把它放在Tkinter循环中时save_f工作，但atexit没有。那么有人能告诉我我做错了什么吗？

Sorry forgot to write atexit the first time. But it's in my code.

编辑：原始代码在这里

import pickle
import atexit
def save_f():
    global register
    outFile = open('Something.txt', 'wb')
    pickle.dump(register, outFile)
    outFile.close()
atexit.register(save_f)

答案

看看你的代码我建议尝试这样做：

def main():
    # ... everything in main ...
    Tkinter.mainloop()

def save_f():
    outFile = open('FobbySave.txt', 'wb')
    pickle.dump(register, outFile)
    outFile.close()

#At Quit
atexit.register(save_f)

if __name__ == "__main__":
    main()

问题可能是您在运行main方法后初始化atexit。因此，在代码被杀死（并停止执行）后，您尝试添加atexit方法。
