问题描述
我正在尝试用双反斜杠替换字符串中的反斜杠或前斜杠.我已经尝试了几件事,但似乎没有用.
我目前的工作:
string = 'C:\Users\Victor\Dropbox\Private\files\test.txt'f = re.sub(r'[\\\/]', '\\\\', 字符串)
这将打印字符串:
'C:\Users\Victor\Dropbox\Private iles est.txt'
但我真正想要的是一个看起来像这样的字符串:
'C:\\Users\\Victor\\Dropbox\\Private\\files\\test.txt'
这样当我打印字符串时,它看起来像原来的
'C:\Users\Victor\Dropbox\Private\files\test.txt'
解决方案
只需将该字符串转换为原始字符串:
<预><代码>>>>字符串 = r'C:\Users\Victor\Dropbox\Private\files\test.txt'>>>细绳'C:\\Users\\Victor\\Dropbox\\Private\\files\\test.txt'>>>打印字符串C:\Users\Victor\Dropbox\Private\files\test.txtI'm trying to replace backslashes or front slashes in a string with double backslashes. I've tried a couple of things but it doesn't seem to work.¨
My work so far:
string = 'C:\Users\Victor\Dropbox\Private\files\test.txt'
f = re.sub(r'[\\\/]', '\\\\', string)
This prints the string:
'C:\Users\Victor\Dropbox\Privateiles est.txt'
But what i really want is a string that looks like this:
'C:\\Users\\Victor\\Dropbox\\Private\\files\\test.txt'
So that when i print the string it will look like the original
'C:\Users\Victor\Dropbox\Private\files\test.txt'
解决方案
Just convert that string to a raw string:
>>> string = r'C:\Users\Victor\Dropbox\Private\files\test.txt'
>>> string
'C:\\Users\\Victor\\Dropbox\\Private\\files\\test.txt'
>>> print string
C:\Users\Victor\Dropbox\Private\files\test.txt
