    import struct
    filepath = "C:test ball.pmd"
    f = open(filepath,"rb")
    data = f.readlines()
    print data
    print
    print"-----------------------"
    print
    f = open(filepath,"rb")
    while 1:
        chunk = f.read(4)
        if chunk == "":
            break
        print struct.unpack('<4b',chunk)
    f.close()
