How to remove duplicates of a single character in string python?

I have a string like this:

but what i want is:

Is there a way to do that?

>Solution :

First of all, if this is a string literal, then it will properly escape the slash, and you will get the result you want:


Otherwise, you could just replace the characters with one of it:

string = string.replace(r'\\', '\\')
