Python rstrip反斜杠

我正试图从一个300万行的大文件中删除字符串“IT\ICCU\LO1\0834426”。但是，当我运行此脚本时，它不会删除字符串。
在Pycharm中编辑脚本时，字符串显示为绿色，但字符“\0”显示为黑色。这是因为反斜杠是转义字符造成的问题吗？有人知道如何解决这个问题吗

with open(f_in, 'r') as fin:
    with open(f_out, 'w') as fout:
        for line in fin:
            if line.rstrip("IT\ICCU\LO1\0834426"):
                fout.write(line)

with open(f_in, 'r') as fin:
    with open(f_out, 'w') as fout:
        for line in fin:
            line = line.replace(r"IT\ICCU\LO1\0834426", "")
            fout.write(line)

您要查找的是函数并使用原始字符串，如下所示：

with open(f_in, 'r') as fin:
    with open(f_out, 'w') as fout:
        for line in fin:
            line = line.replace(r"IT\ICCU\LO1\0834426", "")
            fout.write(line)

            fout.write(line)

rstrip（）用于从字符串右端去除空白字符

with open(f_in, 'r') as fin:
    with open(f_out, 'w') as fout:
        for line in fin:
            line = line.replace(r"IT\ICCU\LO1\0834426", "")
            fout.write(line)

请看string.replace（）。

我不认为OP需要使用原始字符串：

with open(f_in, 'r') as fin:
    with open(f_out, 'w') as fout:
        for line in fin:
            line = line.replace(r"IT\ICCU\LO1\0834426", "")
            fout.write(line)

line =  "JJJJJJJJJJ\IT\ICCU\LO1\0834426\ZZZZZZZZZ"
print line.replace(r"IT\ICCU\LO1\0834426",'')
JJJJJJJJJJ\IT\ICCU\LO1834426\ZZZZZZZZZ

print line.replace("IT\ICCU\LO1\0834426",'')
JJJJJJJJJJ\\ZZZZZZZZZ

使用

line.replace（）
或者至少这是我的解释。

您需要原始字符串文字。但是请阅读
rstrip
——即使使用正确的转义字符串，它也不会像您认为的那样（它可以处理字符集，而不是后缀）。您要做的是使用Re module和Re.sub，您可以将该字符串替换为“”，这样就可以了。通读re模块，它非常有用。您需要原始字符串文本。但是请阅读
