如何读取文本文件导入列表或数组与Python [英] How to read text file into a list or array with Python

问题描述

我想一个文本文件的行读入蟒蛇列表或数组。我只需要能够在创建后在列表或数组单独访问任何项目。

I am trying to read the lines of a text file into a list or array in python. I just need to be able to individually access any item in the list or array after it is created.

该文本文件的格式如下：

The text file is formatted as follows:

0,0,200,0,53,1,0,255,...,0.

凡 ... 是上面有实际的文本文件中有数百或数千项。

Where the ... is above, there actual text file has hundreds or thousands more items.

我用下面的code尝试读取文件到列表：

I'm using the following code to try to read the file into a list:

text_file = open("filename.dat", "r")
lines = text_file.readlines()
print lines
print len(lines)
text_file.close()

我得到的输出是：

The output I get is:

['0,0,200,0,53,1,0,255,...,0.']
1

显然，它是读取整个文件到只有一个项目的列表，而不是单独的项目的列表。我在做什么错了？

Apparently it is reading the entire file into a list of just one item, rather than a list of individual items. What am I doing wrong?

推荐答案

您将有您的字符串拆分为使用拆分值的列表（）

You will have to split your string into a list of values using split()

因此​​，

lines = text_file.read().split(',')
