[issue13409] Invalid expression error if a regex ends with a backslash

[Ezio Melotti]

Ezio Melotti <ezio.melotti at gmail.com> added the comment:

You either have to double escape it (once for python and then for the regex engine) or use raw strings:
>>> re.match("\\\\", '\\').group()
'\\'
>>> re.match(r"\\", '\\').group()
'\\'
