read 4D binary data

[jorge.conrado at cptec.inpe.br]

Hi,


I'm startig in Python and I have a 4D binary data. The dimension of my 
data is:

67 ----> longitude points
41 ----> latitude points
10 ----> pressure levels points
33 ----> time points


How can I read this data and what can I do to get a 2D array 
(longitude,latitude) for a specific pressure  and time dimension.
