Newer versions of Python raise a SyntaxWarning when a regular expression contains a backslash that is not part of an escape sequence. To prevent this warning and future exceptions, use raw strings for all regular expressions. Even strings without escape sequences are converted for consistency. Some IDEs will apply special syntax highlighting to raw strings, which can make it easier to decipher regular expressions.
