将整数转换为数字列表 [英] Converting integer to digit list

问题描述

将integer转换为list的最快，最简洁的方法是什么?

What is the quickest and cleanest way to convert an integer into a list?

例如，将132更改为[1,3,2]，将23更改为[2,3].我有一个变量，它是int，并且我希望能够比较各个数字，因此我认为最好将其放入列表中，因为我可以执行int(number[0])，int(number[1])来轻松转换将该元素返回到int以进行数字运算.

For example, change 132 into [1,3,2] and 23 into [2,3]. I have a variable which is an int, and I want to be able to compare the individual digits so I thought making it into a list would be best, since I can just do int(number[0]), int(number[1]) to easily convert the list element back into int for digit operations.

推荐答案

首先将整数转换为字符串，然后使用map在其上应用int:

Convert the integer to string first, and then use map to apply int on it:

>>> num = 132
>>> map(int, str(num))    #note, This will return a map object in python 3.
[1, 3, 2]

或使用列表理解:

>>> [int(x) for x in str(num)]
[1, 3, 2]
