Python对内部带有整数的字符串排序数组 [英] Python sort array of string with integers inside

问题描述

我如何使用python对列表格式进行排序

How i can use python to sort the list format

format=["12 sheet","4 sheet","48 sheet","6 sheet", "busrear", "phonebox","train"]

喜欢这种方式

format =["4 sheet", "6 sheet", "12 sheet", "48 sheet", "busrear, "phonebox", "train"]

如果数组是列表的列表，那么我们如何做到这一点

edit: If the array is a list of list then how can we do that like this one

format=[[1L, u'12 sheet', 0],[2L, u'4 sheet', 0], [3L, u'48 sheet', 0], [4L, u'6 sheet', 0 [5L, u'Busrear', 0], [6L, u'phonebox', 0], [7L, u'train', 0]]

推荐答案

>>> fmts =["12 sheet","4 sheet","48 sheet","6 sheet", "busrear", "phonebox","train"]
>>> fmts.sort(key=lambda x: (int(x.split(None, 1)[0]) if x[:1].isdigit() else 999, x))
>>> fmts
['4 sheet', '6 sheet', '12 sheet', '48 sheet', 'busrear', 'phonebox', 'train']

format 是内置函数.不要将其用作变量名.它将隐藏内置函数.

format is a builtin function. Do not use it as a variable name. It will shadow the builtin function.
