AttributeError: 'list' 对象在尝试删除 '/n' 时没有属性 'replace' [英] AttributeError: 'list' object has no attribute 'replace' while trying to remove '/n'

问题描述

我有一堆文件需要重命名.我在文本文件中按顺序获得了名称，我需要删除读取文本文件时插入的换行符，但我不断收到此错误.AttributeError: 'list' 对象在尝试删除 '/n' 时没有属性 'replace'

I've got a bunch of files that I need to rename. I've got the names in order in a text file and I need to remove the linebreaks that are inserted when reading the text file, but I keep getting this error. AttributeError: 'list' object has no attribute 'replace' while trying to remove '/n'

感谢任何和所有帮助，我真的不知道我在做什么.

Any and all help is appreciated, I really don't know what I'm doing.

from os import rename, listdir


fnames = listdir('.')
file = open("names.txt", "r")
namelist = [line.split(' ') for line in file.readlines()]
namelist = [n.replace('
', '') for n in namelist]

print (namelist)

推荐答案

问题是split之后namelist中的每个n已经是一个列表字符串.

The problem is that after split each n in namelist already is a list of strings.

如果你想去掉行尾的换行符，你可以把这两种理解颠倒过来，先remove然后split，或者只是合并它们成一.此外，您可以使用 strip 来去除行尾的换行符，而不是 replace.

If you want to remove the newlines at the end of the lines, you can either reverse the two comprehensions, to first remove and then split, or just combine them into one. Also, instead of replace, you can use strip to get rid of the newline character at the end of the line.

namelist = [line.strip().split(' ') for line in file]
