python read binary file
#1
as topics. i want to read a binary file. i need some some offset in it and control by big or little endian. but i have problem with it.

path_xd = 'xxxxx'
pattern = b'\x14\x02'
reg_xd=re.compile(pattern)
with open(path_xd, 'r+b') as p_xd:
    data=p_xd.read()
    for x in reg_xd.finditer(data):
        offset=x.start()
        p_xd.seek(offset)
        data_1402=p_xd.read(16)
        xd_name=int.from_bytes(data_1402[2:4], byteorder='little')
        xd_name=(str(xd_name).replace('0', '')).zfill(2)
        print(xd_name)
        print(data_1402)
        print(data_1402[5:9])
i get output like this
Output:
b'\x14\x02\x01\x00 \x00\x00\x00\x03\x18\x90BW#\x08\x00'
it's how it look like in termial
Output:
402 0100 2000 0000 0318 9042 5723 [..... ......BW# 00000040: 0800 5723 0800
it seems missing some bytes in python output.

i want result like this format. for fullfile. seems i have misunderstand something here. need help with file hex output and big/litte endian please advice.thanks.
Output:
\x14\x02\x01\x00\x20\x00\x00\x00\x03\x18\x90\x42\x57\x23\x08\x00\x57\x23\x08\x00
