Try hard coding it to test, but it probably wants base as the directory and file as the filename:
mapnik.Shapefile(base="C:\\", file=' Ýndice.shp')

message which tells me the file I want to work with
doesn't exist, but it does.

I don't believe you! :-)
Traceback (most recent call last):...

   lyr.datasource = mapnik.Shapefile(base=filepath, file=filepath)
   return CreateDatasource(keywords)
RuntimeError: C:\Ýndice.shp/C:\Ýndice does not exist

That "file name" has two C: in it which I am pretty sure is
an illegal path in Windows. Therfore the file cannot exist.

You just need to build your path correctly I suspect.
