From page 132 in the numpy book:
The fields dictionary is indexed by keys that are the names of the fields. Each entry in the dictionary is a tuple fully describing the field: (dtype, offset[,title]). If present, the optional title can actually be any object (if it is string or unicode then it will also be a key in the fields dictionary, otherwise it’s meta-data).
I should read it more often...
I put the titles in as a sort of additional documentation, and thinking that they might be useful for labeling plots;
That's actually quite a good idea...
but it is rather hard to get the titles back out, since they are not directly accessible as an attribute, like names. Probably I should just omit them.
We could perhaps try a function: def gettitle(dtype, name): try: field = dtype.fields[name] except (TypeError, KeyError): return None else: if len(field) > 2: return field[-1] return None
