固定大小
代码语言:javascript复制from functools import partial
i = 0
f = open('lgtm-monitor.dat', 'rb')
f2 = open('f.txt', 'w')
records = iter(partial(f.read, 2), b'') # 每次2字节
for r in records:
j = 0
r_int = int.from_bytes(r, byteorder='big') #将 byte转化为 int
i = 1
print('i={0}:{1}'.format(i, r_int))
f2.write(str(r_int) ' ')
if 8==i:
f2.write('n')
i = 0
break
f.close()
f2.close()
二进制文件使用 read( size)

data = fp.read(2) #type(data) === bytes
text = int.from_bytes(data, byteorder='big')
fp.close()
