Deprecation warning due to invalid escape sequences

Description

Deprecation warnings are raised due to invalid escape sequences in Python 3.8 . Below is a log of the warnings raised during compiling all the python files. Using raw strings or escaping them will fix this issue.

find . -iname '*.py'  | xargs -P 4 -I{} python -Wall -m py_compile {}

Yes, they were also present in Python 3.7 . In Python 3.8 they were made SyntaxWarning but got reverted later to deprecation warning since a lot of libraries were not fixed extending the deprecation period.
