Python3 显示bytes中的值

根据这个图，结合struct

def DispBytes(b):

'''把 bytes 中相应的值转成字串后输出

t = b'\x023\x02' --> DispBytes(t) '02 33 02'

'''

import struct

disp = ''

if type(b) == bytearray:

b = bytes(b)

if type(b) == bytes:

tup = struct.unpack('B'*len(b),b)# 转换成元组

ls = list(tup)

for i in range(len(ls)):

if(i == 0):

disp += '{0:02X}'.format(ls[i])

else:

disp += ' {0:02X}'.format(ls[i])

return disp
