Python 打印已排序的列表无法完全工作，如何解决此问题？

我编写的代码：

opener = open("gymclub.txt", "r")
reader = opener.readline()
listObjects = []
listNames = []
listPressups = []
listPullups = []
sortedListPressups = []
while reader!="":
    splitting=reader.split(",")
    name = splitting[0]
    press_ups = splitting[1]
    pull_ups = splitting[2]
    reader = opener.readline()
    listPressups.append(press_ups)
    sortedListPressups = sorted(listPressups, reverse = True)
print(sortedListPressups)

结果：

['8', '75', '74', '73', '67', '66', '58', '45', '33', '30', '25', '10']

预期结果：

['75', '74', '73', '67', '66', '58', '45', '33', '30', '25', '10','8']

我做错了什么

编辑：这是文本文件：

你在排序字符串，而不是数字

>>> '8' > '75' 符合事实的 如果要根据这些元素的整数值对其进行排序，可以在排序时传递键参数。这将保持原始数组不变

>>>sortedlistPressups，key=int，reverse=True ['75', '74', '73', '67', '66', '58', '45', '33', '30', '25', '10', '8']

您需要将读取的行从字符串转换为整数。现在已排序按字典顺序对列表中的字符串进行排序

opener=opengymclub.txt，r reader=opener.readline listObjects=[] listNames=[] listPressups=[] listPullups=[] sortedListPressups=[] 而读者！=： spliting=reader.split， 名称=正在拆分[0] 按_ups=拆分[1] 上拉=拆分[2] reader=opener.readline listPressups.appendintpress\u ups listPressups.sortreverse=True 打印列表 我已经为你从循环中取出来了。不需要每次迭代都对整个列表进行排序。 我还使用list.sort而不是sorted对列表进行适当排序。 如果您确实希望保留列表中的项目为字符串的行为，则可以使用key参数并为其提供一个排序依据的函数：

listPressups.sort(key=int, reverse=True)

由于元素是字符串，因此当前按字典顺序进行排序。要将它们按数字格式化，必须将它们转换为数字。对于任何列表，您都可以按如下方式进行操作

arr = ['8', '75', '74', '73', '67', '66', '58', '45', '33', '30', '25', '10']
print(sorted(list(map(int,arr)),reverse=True)) 

输出：

所以，在你的情况下，你可以这样做

opener = open("gymclub.txt", "r")
reader = opener.readline()
listObjects = []
listNames = []
listPressups = []
listPullups = []
sortedListPressups = []
while reader!="":
    splitting=reader.split(",")
    name = splitting[0]
    press_ups = splitting[1]
    pull_ups = splitting[2]
    reader = opener.readline()
    listPressups.append(press_ups)
    sortedListPressups = (sorted(list(map(int,listPressups)),reverse=True))
print(sortedListPressups)

输出：

如果希望最终列表像最初一样是字符串列表本身，那么也可以按照以下方式进行

opener = open("gymclub.txt", "r")
reader = opener.readline()
listObjects = []
listNames = []
listPressups = []
listPullups = []
sortedListPressups = []
while reader!="":
    splitting=reader.split(",")
    name = splitting[0]
    press_ups = splitting[1]
    pull_ups = splitting[2]
    reader = opener.readline()
    listPressups.append(press_ups)
    sortedListPressups = sorted(listPressups, reverse = True, key = int)
print(sortedListPressups)

输出：

如果要就地排序，还可以执行sortedListPressups.sortreverse=True，key=int而不是使用sorted。您可以阅读有关这些方法的更多信息

对字符进行排序将导致此结果。您需要将字符串元素强制转换为数字：

opener = open("gymclub.txt", "r")
reader = opener.readline()
listObjects = []
listNames = []
listPressups = []
listPullups = []
sortedListPressups = []
while reader!="":
    splitting=reader.split(",")
    name = splitting[0]
    press_ups = int(splitting[1])
    pull_ups = splitting[2]
    reader = opener.readline()
    listPressups.append(press_ups)
    sortedListPressups = sorted(listPressups, reverse = True)
print(sortedListPressups)

也许你可以分享gymclub.txt如何让其他人复制你的大小写。字符串按字典顺序排序，即按字母顺序排序

opener = open("gymclub.txt", "r")
reader = opener.readline()
listObjects = []
listNames = []
listPressups = []
listPullups = []
sortedListPressups = []
while reader!="":
    splitting=reader.split(",")
    name = splitting[0]
    press_ups = splitting[1]
    pull_ups = splitting[2]
    reader = opener.readline()
    listPressups.append(press_ups)
    sortedListPressups = sorted(listPressups, reverse = True, key = int)
print(sortedListPressups)

['75', '74', '73', '67', '66', '58', '45', '33', '30', '25', '10','8']

opener = open("gymclub.txt", "r")
reader = opener.readline()
listObjects = []
listNames = []
listPressups = []
listPullups = []
sortedListPressups = []
while reader!="":
    splitting=reader.split(",")
    name = splitting[0]
    press_ups = int(splitting[1])
    pull_ups = splitting[2]
    reader = opener.readline()
    listPressups.append(press_ups)
    sortedListPressups = sorted(listPressups, reverse = True)
print(sortedListPressups)
