Python 如何按顺序排列时间?

Python 如何按顺序排列时间?,python,sorting,timer,tkinter,Python,Sorting,Timer,Tkinter,我是python新手。 基本上我做这个GUI是为了记录一辆车的圈速。一旦赛车完成第一圈,我就要记录第一圈的计时。随后的圈数也需要记录。记录的时间将显示在列表框中。但是,我不知道如何将时间从最快的实验室时间排序到最慢的实验室时间。有人能帮我吗 from tkinter import * import time class StopWatch(Frame): """ Implements a stop watch frame widget.

通常,经过的时间将存储在一个列表中,然后列表将按照您想要的顺序进行排序。我不知道你是否已经这样做了,但是作为一个现有列表上的简单示例,尝试一下这个,并在文件中看到结果


问题出在代码的哪一部分?不要发布一堆与你要问的问题无关的代码。@Erik Godard代码没有问题。基本上我只知道如何分类。我是python新手,我对中止排序没有任何了解。这就是我需要你们帮助我的原因。你们做了什么来解决这个问题?例如,您在python文档中查找过单词“sort”吗?@BryanOakley我能知道对我上面的代码有帮助的链接是什么吗?仅此网站就有12000多个关于python排序的问题:
    def GravaCSV(self):
        arquivo = str(self.e.get()) + ' - '
        self.laps.sort()
        """ next sort as numbers instead of strings (not tested)
            and then sort and write laps_as_num to file
        laps_as_num=[]
        for this_lap in laps:
            lap=this_lap.split(":")
            laps_as_num.append([int(lap[0]), int(lap[1]), int(lap[2])])
        """
        with open(arquivo + self.today + '.txt', 'wb') as lapfile:
                for Lap in self.laps:
                    lapfile.write((bytes(str(Lap) + '\n', 'utf-8')))
