Inserted raw strings because Python3 interpretes string literals as Unicode strings,
so '\d' is considered an invalid escaped sequence but this is not the case.
This fix avoids the "SyntaxWarning: invalid escape sequence '\d'" warning
for Python versions greater than 3.6.

    v1: inserted raw strings to avoid SyntaxWarning in Python3
