python replace backslashes to slashes

问题

How can I escape the backslashes in the string: 'pictures\12761_1.jpg'?

I know about raw string. How can I convert str to raw if I take 'pictures\12761_1.jpg' value from xml file for example?

You can use the string .replace() method.

>>> print r'pictures\12761_1.jpg'.replace("\\", "/")
pictures/12761_1.jpg

You can also use split/join:

print "/".join(r'pictures\12761_1.jpg'.split("\\"))

EDITED:

The other way you may use is to prepare data during it's retrieving(e.g. the idea is to update string before assign to variable) - for example:

f = open('c:\\tst.txt', "r")
print f.readline().replace('\\','/')

>>>'pictures/12761_1.jpg\n'
