Issue #208 Fix "invalid escape sequence" warnings before they become errors
Description
Escape "\" in regular expressions. A single backslash "\" is the Python escape character. To code the escape character "\" in regular expressions, the backslash itself needs to be escaped as "\\".
Motivation and Context
Per https://docs.python.org/3/library/re.html, the "invalid escape sequence" Syntax Warning will become a Syntax Error in a future version of Python:
Specifically, this PR corrects the cause of the following Syntax Warning messages, so that they will not cause a failure when Python is updated and they become Syntax Errors.
