SyntaxError raised due to improper use of escape sequence "\s*"

[diegodebrito]

I am getting a SyntaxError when debugging some code. The error is related to an invalid use with \ in the context of string matching (see link for exact line below).

re.finditer('{0}\s*'.format(re.escape(sent)), self.original_text)

Which raises the following error:

E     File "local\.venv\Lib\site-packages\pysbd\segmenter.py", line 66
E       for match in re.finditer('{0}\s*'.format(re.escape(sent)), self.original_text):
E                                ^^^^^^^^
E   SyntaxError: invalid escape sequence '\s'
