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

问题描述

我试图让 Python 从 .txt 文件读取一行并将第一行的元素写入列表.文件中的元素是制表符分隔的，所以我使用 split(" ") 来分隔元素.因为 .txt 文件有很多元素，所以我将每行找到的数据保存到一个单独的列表中.

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(" ") 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每个列表是这样的:

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
']

如何从列表的最后一个元素中删除 并使其成为 '7.3' ?

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

推荐答案

如果您只想从最后一个元素中删除 ，请使用:

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

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

如果要从所有元素中删除 ，请使用:

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

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

您也可以考虑在拆分行之前删除 :

You might also consider removing before splitting the line:

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