如何使用python将我的字节数据转换为整数？

Question

I have a byte data is like: b'\\xc4\\x03\\x00\\x00\\xe2\\xecqv\\x01' .
How do I convert this to integer like index by index.

Answer 1

a bytes object is basically already a (immutable) sequence of integers.

b = b'\xc4\x03\x00\x00\xe2\xecqv\x01'
b[0] # 196
lst = list(b)
#  [196, 3, 0, 0, 226, 236, 113, 118, 1]

Answer 2

Just access throug indexes:

>>> b = b'\xc4\x03\x00\x00\xe2\xecqv\x01'
>>> b[0]
196

>>> for i in b:
...     print(i)
... 
196

0
226
236
113
118

Answer 3

如果你有Python v.3，你可以使用int_from_bytes（）函数：

int.from_bytes(b'\xc4\x03\x00\x00\xe2\xecqv\x01', byteorder='big')
