如何对数字字符串的python列表进行排序 [英] How to sort python list of strings of numbers

问题描述

我正在尝试对包含数字的字符串列表进行排序

a = ["1099.0","9049.0"]a.sort()一种['1099.0', '9049.0']b = ["949.0","1099.0"]b.sort()乙['1099.0', '949.0']一种['1099.0', '9049.0']

但是列表 b 是排序而不是列表 a

解决方案

您想根据 float 值(不是字符串值)进行排序，请尝试:

<预><代码>>>>b = ["949.0","1099.0"]>>>b.sort(key=float)>>>乙['949.0', '1099.0']

I am trying to sort list of strings containing numbers

a = ["1099.0","9049.0"]
a.sort()
a
['1099.0', '9049.0']

b = ["949.0","1099.0"]
b.sort()    

b
['1099.0', '949.0']

a
['1099.0', '9049.0']

But list b is sorting and not list a

解决方案

You want to sort based on the float values (not string values), so try:

>>> b = ["949.0","1099.0"]
>>> b.sort(key=float)
>>> b
['949.0', '1099.0']
