[Numpy-discussion] blank values '--'

Hello,
I am loading in data from the GRIB2 files using PyNIO. Once I load them
into numpy arrays I am left with a halo of values near the array
boundaries that appear to be empty. When I print them or use them in
conditional statements I see values of '--'. I'd like to turn these
values into zeroes at the very least.
As an example if I print the array I see:
[[-- -- -- ..., -- -- --]
[-- -- -- ..., -- -- --]
[-- -- -- ..., -- -- --]
...,
[-- -- -- ..., -- -- --]
[-- -- -- ..., -- -- --]
[-- -- -- ..., -- -- --]]
though I know that there are valid values in the interior of the domain
which plot properly.
I can't find anything in the numpy documentation that addresses this
type of missing value. Has anyone dealt with this before?
Thanks,
Bryan
