本文介绍了从Python中的文件中读取行而不会得到“\ n”附在最后的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧! 问题描述 29岁程序员,3月因学历无情被辞! 我的文件是xml.txt,内容如下: books.xml news.xml mix.xml 如果使用readline()函数,它附加\\\at所有文件的名称,因为我想打开xml.txt中包含的文件是错误的。我写了这个: $ $ p $ fo = open(xml.tx,r) (count .__ len __()):#here count是可能数组之一,我使用 file = fo.readline() find_root(file)#这里find_root是我自己创建的函数不显示这里 运行此代码时遇到错误: '解决方案 line = line.rstrip('\\\') $ b 原因 readline 保持换行符,所以你可以区分一个空行(有换行符)和文件的结尾(空字符串)。My file is "xml.txt" with following contents:books.xmlnews.xmlmix.xmlif I use readline() function it appends "\n" at the name of all the files which is an error because I want to open the files contained within the xml.txt. I wrote this:fo = open("xml.tx","r")for i in range(count.__len__()): #here count is one of may arrays that i'm using file = fo.readline() find_root(file) # here find_root is my own created function not displayed hereerror encountered on running this code:IOError: [Errno 2] No such file or directory: 'books.xml\n' 解决方案 To remove just the newline at the end:line = line.rstrip('\n')The reason readline keeps the newline character is so you can distinguish between an empty line (has the newline) and the end of the file (empty string). 这篇关于从Python中的文件中读取行而不会得到“\ n”附在最后的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持! 上岸,阿里云!
