Python从文件中读取字符串并将其拆分为值 [英] Python read in string from file and split it into values

问题描述

我有一个格式如下的文件:

I have a file in the format below:

995957,16833579
995959,16777241
995960,16829368
995961,50431654

我想读每一行，但将这些值分成适当的值.例如，第一行将被拆分为:

I want to read in each line but split the values into the appropriate values. For example the first line would be split into:

x = 995957
y = 16833579

由于当您读入它时它是一个字符串，并且我想将它们转换为一个int并将它们拆分，所以我该怎么做呢?任何帮助将不胜感激.

Since its a string when you read it in and I want to convert them to an int and split them, how exactly would I go about doing this? Any help would be appreciated.

谢谢！

推荐答案

类似的事情-对于读入字符串变量a的每一行:

Something like this - for each line read into string variable a:

>>> a = "123,456"
>>> b = a.split(",")
>>> b
['123', '456']
>>> c = [int(e) for e in b]
>>> c
[123, 456]
>>> x, y = c
>>> x
123
>>> y
456

现在，您可以对分配的x和y(它们是整数)进行必要的操作.

Now you can do what is necessary with x and y as assigned, which are integers.
