Using str.replace method changes nothing in the original string

Question

I need to compare paths. In a textile, I get paths like:

'C:\\\\Windows\\\\System32\\\\kernel32.dll'

The other path I get from the command line.

To compare the two strings I tried:

while path.find('\\') != -1:
    path.replace('\\\\','\\', 1)

but this changes nothing. Also the builtin functions os.path.normpath() and os.path.realpath() don't remove the backslashes. How to remove the backslashes from the string?

did you try ? http://stackoverflow.com/questions/3160752/removing-backslashes-from-a-string-in-python — Sohan, May 11 '17 at 13:30

In C# you need to assign the return value from replace. Something like that:

path = path.replace('\\\\','\\', 1)

but I think you are using Java and I don't know if is the same, but try it

This is python, look at the tag. Als `while ... :` is obviously python. – Ludisposed May 11 '17 at 13:51

to replace 2 \ by one \ , you can do like that:

value = "C:\\\\Windows\\\\System32\\\\kernel32.dll"
print value.replace("\\\\", "\\")

gives me:

C:\Windows\System32\kernel32.dll

Try:

path = path.replace('\\\\','\\', 1)

This returns a single backslash and can be compared to output from os.getcwd()

path = path.replace('\\\\', '\\')
