The test code:
Tf=open (T.b 'in' and 'wb)
Tf. Write (struct. Pack (' & lt; HHHH ', width, hight, format_ pixel_size))
Tf. The close ()

Code is so simple, struct. Pack (' & lt; HHHH ', 134, 38, 1, 4) print is no problem, format is b '\ x86 \ x00 \ x26 \ x00 \ x01 \ x00 \ x04 \ x00'
But the bin file data only c2 86 26 01 04
Rather than the expected 86 00 00 26 01 00 00 04
Excuse me what reason be?
