Before this PR, the stub file
_savitzky_golay.pyi
had untyped annotations. This PR adds in the missing type annotations and improves previous ones.The improvements are:
op.CanIndex
instead ofint
for theaxis
parameter.use
andmode
parametersThis file tends to use
int
andfloat
a lot which could perhaps be replaced byAnyInt
andAnyReal
however, some parameters likewindow_length
are used as shapes in calls to functions likenp.zeros
which don't acceptnp.bool_
.For simplicity I left the type annotations as the builtin python types but I am open to using more general type annotations to allow numpy dtypes as well. It just might take a bit more testing to check the allowed types.
