Hi guys, can you please fix this very minor issue (this is a warning raised by pytest):

hamilton\function_modifiers\macros.py:1522: SyntaxWarning: invalid escape sequence '\*'

What needs to be done is add a

r

to the beginning of the docstring (i.e.

"""

->

r"""

) and change

\*\*

on the aforementioned line to

**

.

Happy to fix shortly — if it’s a blocker I can also approve a PR and release a patch version sooner!

Nah, not a blocker (unless someone fails their test suite on warnings). I should mention that this was observed in a project that imports hamilton, not in hamilton itself (although the warning should appear there too)

Yep will fix!

Huh, interesting, that warning doesn't show up when I run pytest.. I ran

pytest tests/function_modifiers/test_macros.py

where the

mutate

tests are located. Also, the suggested fix errors out with

hamilton/hamilton/function_modifiers/macros.py:docstring of hamilton.function_modifiers.macros.mutate.__init__:8:Inline strong start-string without end-string.
Sphinx exited with exit code: 2

which I think comes form an

rst

compilation issue. Putting ``**kwargs`` seems to fix the issue and I think it might not raise a pytest error.
