Python strip 函数仅适用于字符串的左侧

发布于 2025-01-20 11:34:41 字数 504 浏览 3 评论 0原文

我有一个文本行的文件，我想剥离第一个和最后一个字符，然后将剥离的行存储在列表中。文本类似于：

％5 SDGFJFHLSJF％5 ％5 alkdregtrlkjdls％5 ％5 dgglssj％5

为了摆脱领先和尾随的字符（％5），我在几种代码中使用了剥离功能，但我没有得到预期的结果。领导角色被剥离，但尾随的角色仍然存在：

SDGFJFHLSJF％5 alkdregtrlkjdls％5 DGGLSSJ％5

这是我目前尝试实现的代码：

    stripped = []        
    with open ('/path/testfile') as file:
        for line in file.readlines():
            strippedline = line.strip("%5")
            stripped.append(strippedline)

有人可以告诉我我的错误是什么？

谢谢

I have a file with text lines that I want to strip the first and last characters and then store the stripped lines in a list. The text is something like:

%5 sdgfjfhlsjf %5
%5 alkdregtrlkjdls %5
%5 dgglssj %5

In order to get rid of the leading and trailing characters (%5), I used the strip function in a few variants of code, but I didn't get the expected result. The leading characters are stripped, but the trailing ones are still in place:

sdgfjfhlsjf %5
alkdregtrlkjdls %5
dgglssj %5

This is code I try to implement at the moment:

    stripped = []        
    with open ('/path/testfile') as file:
        for line in file.readlines():
            strippedline = line.strip("%5")
            stripped.append(strippedline)

Can someone tell me what my mistake(s) is?

Thanks

strip 删除两端的字符。就您而言，主要问题是每行末尾都有 \n ，因此您的代码也应该删除它：

stripped = []        
with open ('/path/testfile') as file:
    for line in file.readlines():
        strippedline = line.strip("\n%5")
        stripped.append(strippedline)

strip removes characters from both ends. In your case, the main issue though is that you have \n at the end of each line, so your code should remove that as well:

stripped = []        
with open ('/path/testfile') as file:
    for line in file.readlines():
        strippedline = line.strip("\n%5")
        stripped.append(strippedline)
