从Python中的现有文件中选择一些单词 [英] Select some words from an existing file in Python

问题描述

我想使用'endswith'分隔以某个字符串结尾的文本文件( text.txt )的确切单词.事实是我的变量

I want to separate the exact words of a text file (text.txt) ending in a certain string by using 'endswith'. The fact is that my variable

h=[w for w in 'text.txt' if w.endswith('os')] 

在我打电话时没有给出我想要的东西.另一方面，如果我尝试命名打开的文件

does not give what I want when I call it. On the other hand, if I try naming the open file

f=open('text.txt')
h=[w for w in f if w.endswith('os')]

也不起作用.我应该先将文本转换为列表吗?

does not work either. Should I convert the text into a list first?

评论:我希望这不是重复的.与此

Comment: I hope this is not duplicate. It is not the same as this former question although close to it.

推荐答案

首先打开文件，然后按以下方式对其进行处理:

Open the file first and then process it like this:

with open('text.txt', 'r') as file:
        content = file.read()
h=[w for w in content.split() if w.endswith('os')]
