Sorry, I didn't specify it correctly. It is "numpy.lib.recfunctions".thanks -- found it.Also, the functions in that module encourage "pandas-like" use of
structured arrays, but I'm not sure they should be used that way. I've
been thinking they should be primarily used for binary interfaces
with/to numpy, eg to talk to C programs or to read complicated binary files.that's my use-case. And I agree -- if you really want to do that kind of thing, pandas is the way to go.I thought recarrays were pretty cool back in the day, but pandas is a much better option.So I pretty much only use structured arrays for data exchange with C code....
