Hello,

I want to read from a binary file called myaudio.dat
Then I've tried the next code:

import struct
name = "myaudio.dat"
f = open(name,'rb')
f.seek(0)
chain = "< 4s 4s I 4s I 20s I I i 4s I 67s s 4s I"
s = f.read(4*1+4*1+4*1+4*1+4*1+20*1+4*1+4*1+4*1+4*1+4*1+67*1+1+4*1+4*1)

FYI, the struct module has a function called 'calcsize', so:

    s = f.read(struct.calcsize(chain))
