[PYTHON MATRIX-SIG] How time-consuming is array()?

[janko hauser]

Now I have some functions in my analysis-pack and encounter, that most
time is spent in reading the data, although I use the netcdf-package
of Bill Noon.

With this package I can read binary NetCDF-files, but the fields are
returned as nested lists.

X=array((f_head.var('xp')),Float32)

Is the translation from a list to an array very timeconsuming or is
the reading in the NetCDF-package the costly operation?
