Hello, 

i am looking for a Python module for reading HDF4 data.
I know that there exist a module for HDF5, but unfortunately 
HDF5 is not compatible to HDF4. 

I tried the following for reading HDF4 data, but this
is faulty and dowdy:

def hdfdump(hdffile,var):
    key="Data-Set-"
    os.system("ncdump -v "+key+var+" "+hdffile+"> /tmp/hdffile")
    f=open('/tmp/hdffile','r')
    a=f.read()
    f.close()
    findexp=key+var+" ="# Data-Set-4 = 23424,23123,..
    s1=find(a,findexp)
    s2=find(a,";",s1)
    b=a[s1+len(findexp):s2]
    return b



Thank you very much for your help,

Regards,
