如何从列表元素中删除\ n? [英] How to remove \n from a list element?

问题描述

我正在尝试将Python从.txt文件中读取到一行，并将第一行的元素写入列表中.文件中的元素用制表符分隔，因此我使用split("\t")分隔了元素.由于.txt文件包含很多元素，因此我将在每一行中找到的数据保存到单独的列表中.

I'm trying to get Python to a read line from a .txt file and write the elements of the first line into a list. The elements in the file were tab- separated so I used split("\t") to separate the elements. Because the .txt file has a lot of elements I saved the data found in each line into a separate list.

我目前遇到的问题是，它显示这样的每个列表:

The problem I currently have is that it's showing each list like this:

['Name1', '7.3', '6.9', '6.6', '6.6', '6.1', '6.4', '7.3\n']

如何从列表的最后一个元素中删除\n并将其设置为'7.3'?

How can I remove \n from the last element of the list and make it just '7.3'?

推荐答案

如果只想从最后一个元素中删除\n，请使用以下方法:

If you want to remove \n from the last element only, use this:

t[-1] = t[-1].strip()

如果要从所有元素中删除\n，请使用以下方法:

If you want to remove \n from all the elements, use this:

t = map(lambda s: s.strip(), t)

您还可以考虑在分割行之前\n :

You might also consider removing \n before splitting the line:

line = line.strip()
# split line...
