pyseeyou is unmaintained and has invalid escape sequences

[jpmckinney]

These invalid escape sequences are upgraded to syntax errors if running code with -W error.

There is an abandoned PR to fix it here: https://github.com/rolepoint/pyseeyou/pull/17/files

The package is essentially unmaintained.

It would be great if this dependency were removed, or if it were made optional (as a package extra). In future Python versions, these warnings will be errors even without -W error.

A backslash-character pair that is not a valid escape sequence now generates a SyntaxWarning, instead of DeprecationWarning. For example, re.compile("\d+.\d+") now emits a SyntaxWarning ("\d" is an invalid escape sequence, use raw strings for regular expression: re.compile(r"\d+.\d+")). In a future Python version, SyntaxError will eventually be raised, instead of SyntaxWarning. (Contributed by Victor Stinner in gh-98401.)

Agree we keep getting these warnings now.

<unknown>:1: SyntaxWarning: invalid escape sequence '\w'
<unknown>:1: SyntaxWarning: invalid escape sequence '\w'
<unknown>:1: SyntaxWarning: invalid escape sequence '\w'
<unknown>:1: SyntaxWarning: invalid escape sequence '\.'
<unknown>:1: SyntaxWarning: invalid escape sequence '\s'

It's really annoying not knowing where the errors come from so hopefully this comment will help finding possible sources, transifex-python is one of them.
