Question

I am trying to read a binary file (only 32 bits long) into a boolean array. It worked just fine when I followed:

Using Python How can I read the bits in a byte?

However, when I try to use the struct package I get a different results:

_fmt = '32?'

with open(filename, mode='rb') as fp:
    content = struct.unpack(fmt, fp.read(struct.calcsize(fmt))

I would like to understand why.

Thanks

Answer 1

The format '32?' indicates 32 bytes, not 32 bits.
