Deprecation and syntax warnings in Python 3.8

[tirkarthi]

• Deprecation warning due to invalid escape sequences. Using raw strings or escaping them again helps in resolving this.
• Syntax warnings due to comparison of literals using is.

Check https://github.com/asottile/pyupgrade/ for automatic fix of this.

The SyntaxWarnings in non-test code would be fixed in #1612.
