Research direction
Start with the string literals reported in tests/test_write.py at lines 8 and 14, then run the relevant test file under Python 3.8 or newer. Done means the tests still pass and no invalid escape sequence SyntaxWarning is emitted for these cases.
Written by the indexing model from the issue text.
Description
These warnings are new with python 3.8 (see the "Changed in version 3.8" note at the end of https://docs.python.org/3.8/reference/lexical_analysis.html#string-and-bytes-literals ):
