Thanks. No, it's not what I'm looking for.
I'm looking for the code that parses the string "<i8" in the npy file array
header's descriptor:
{'descr': '<i8', 'fortran_order': False, 'shape': (5,), }
There are many different descriptor strings, e.g.:
'>f8'
'=f4'
'float32'
'>c16'
...
Ideally, I want the exhaustive list of valid input strings that describe
standard ndarrays (i.e. ndarrays with simple entries as opposed to records
or subarrays). Lacking an exhaustive list or spec, I'd like the source code
that does the parsing for them. This stackoverflow post is worth looking
at:

Thanks again,
Ted
