Question

我的tkinter窗口中的时钟导致整个窗口崩溃。我知道这一点，因为当我评论它时，它完美无缺。有什么方法可以调整或重组代码以防止崩溃？崩溃通常发生在运行时5-10秒。

以下是整个计划

时钟/日期变量和update_clock（）函数是有问题的。

def dateconverter():
    global today
    if today[0].lower() == '0' and today[1].lower() == '1':
        today = 'January'+' '+time.strftime("%d")
    if today[0].lower() == '0' and today[1].lower() == '2':
        today = 'February'+' '+time.strftime("%d")
    if today[0].lower() == '0' and today[1].lower() == '3':
        today = 'March'+' '+time.strftime("%d")
    if today[0].lower() == '0' and today[1].lower() == '4':
        today = 'April'+' '+time.strftime("%d")
    if today[0].lower() == '0' and today[1].lower() == '5':
        today = 'May'+' '+time.strftime("%d")
    if today[0].lower() == '0' and today[1].lower() == '6':
        today = 'June'+' '+time.strftime("%d")
    if today[0].lower() == '0' and today[1].lower() == '7':
        today = 'July'+' '+time.strftime("%d")
    if today[0].lower() == '0' and today[1].lower() == '8':
        today = 'August'+' '+time.strftime("%d")
    if today[0].lower() == '0' and today[1].lower() == '9':
        today = 'September'+' '+time.strftime("%d")

我不知道这是否是唯一的问题，但有一个问题是您从update_clock开始两次调用update_clock。你打电话给它一次，它会在＆＃34;＆＃34;之后添加两个工作。队列。一项工作在运行时就会结束，并且还会增加两项工作。现在有三个。接下来又增加了两个，所以有四个。一个是关闭但你再添加两个，所以有五个，依此类推，然后每秒发生两次。
