[python] binary data write to file

# binary data generation
bdata = bytes(range(0, 256))

# check length and data
print('size :', len(bdata), '\ndata : ', bdata)

# set offset and chunk size, get data size
offset = 0
chunk = 10
size = len(bdata)

# write to file and get size
with open('bfile.bin', 'wb') as bf:
    while offset <= size:
        bf.write(bdata[offset:offset+chunk])
        offset += chunk

# check file
! cat bfile.bin
