read data from input file stream

Hi guys,

I have the following method defined in python :

def amrPayload2Storage_OctetAlignedMode(payload):
    try:
        # assume no interleaving, CRCs or bit re-ordering
        bitlen = [95,103,118,134,148,159,204,244,39]
        amr = BitArray(bytes=payload)
        cmr = amr[0:4]
        res = amr[4:8]
        assert res.uint==0,'amr[4:8] must be zero'
        f = amr[8]
        mode = amr[9:13]
        qual = amr[13:14]
        pad = amr[14:16]
        if mode.uint >=0 and mode.uint <= 8:
            assert amr.len >= 16+bitlen[mode.uint]
            voice = amr[16:16+bitlen[mode.uint]]
            storage = BitArray(bin='0')
            storage.append(mode)
            storage.append(qual)
            storage.append('0b00') # padding
            assert storage.len==8,"check length of storage header is one byte"
            storage.append(voice)
            return storage.tobytes()
    except:
	import pdb
#    pdb.pm() # or pdb.post_mortem()
	pdb.set_trace()
    return ''

I want to read the data from an input file and pass it to the function, I need help on how to do that?

Thanks

with open('thefile.data', 'rb') as f:
    payload = f.read()

Now you have your payload ready.
