I see it. The problem is that the user input variable "weights" is used
down the line, as opposed to the object created in the try/except blocks.
The list `wt` is not so useful, so I would probably define something
that's guaranteed to be a function, like so:
{{{
if callable(weights):
wts = weights
else:
wts = lambda x: weights[x]
}}}
Then use wts instead of weights down the line.
For the record, to test a file, run (from the top `sage` directory):
{{{
./sage -t src/sage/matroids/matroid.pyx
}}}
