I'm trying to replace all double backslashes with just a single backslash. I want to replace 'class=\\"highlight' with 'class=\"highlight'. I thought that python treats '\\' as one backslash and r'\\+' as a string with two backslashes. But when I try
In [5]: re.sub[r'\\+', '\\', string]
sre_constants.error: bogus escape [end of line]
So I tried switching the replace string with a raw string:
In [6]: re.sub[r'\\+', r'\\', string]
Out [6]: 'class=\\"highlight'
Which isn't what I need. So I tried only one backslash in the raw string:
In [7]: re.sub[r'\\+', r'\', string]
SyntaxError: EOL while scanning string literal

why not use string.replace[]?
>>> s = 'some \\\\ doubles'
>>> print s
some \\ doubles
>>> print s.replace['\\\\', '\\']
some \ doubles
Or with "raw" strings:
>>> s = r'some \\ doubles'
>>> print s
some \\ doubles
>>> print s.replace['\\\\', '\\']
some \ doubles
Since the escape character is complicated, you still need to escape it so it does not escape the '

You only got one backslash in string:
>>> string = 'class=\\"highlight'
>>> print string
class=\"highlight
Now lets put another one in there
>>> string = 'class=\\\\"highlight'
>>> print string
class=\\"highlight
and then remove it again
>>> print re.sub['\\\\\\\\', r'\\', string]
class=\"highlight

Just use .replace[] twice!
I had the following path: C:\\Users\\XXXXX\\Desktop\\PMI APP GIT\\pmi-app\\niton x5 test data
To convert \ to single backslashes, i just did the following:
path_to_file = path_to_file.replace['\\','*']
path_to_file = path_to_file.replace['**', '\\']
first
operation creates ** for every \ and second operation escapes the first slash, replacing ** with a single \.
Result:
C:**Users**z0044wmy**Desktop**PMI APP GIT**pmi-app**GENERATED_REPORTS
C:\Users\z0044wmy\Desktop\PMI APP GIT\pmi-app\GENERATED_REPORTS

I just realized that this might be the simplest answer:
import os
os.getcwd[]
The above outputs a path with \ [2 back slashes]
BUT if you wrap it with a print function, i.e., print[os.getcwd[]] it will output the 2 slashes with 1 slash so you can then copy and paste into an address bar!
