从python中的unicode字符串获取字节 [英] getting bytes from unicode string in python

问题描述

我有一个16位大端字节序Unicode字符串，表示为 u'\u4132'，

I have an 16bit big endian unicode string represented as u'\u4132',

我在python中将其分为41和32的整数？

how can I split it into integers 41 and 32 in python ?

推荐答案

以下是您可能需要的各种不同方式。

Here are a variety of different ways you may want it.

Python 2：

>>> chars = u'\u4132'.encode('utf-16be')
>>> chars
'A2'
>>> ord(chars[0])
65
>>> '%x' % ord(chars[0])
'41'
>>> hex(ord(chars[0]))
'0x41'
>>> ['%x' % ord(c) for c in chars]
['41', '32']
>>> [hex(ord(c)) for c in chars]
['0x41', '0x32']

Python 3：

>>> chars = '\u4132'.encode('utf-16be')
>>> chars
b'A2'
>>> chars = bytes('\u4132', 'utf-16be')
>>> chars  # Just the same.
b'A2'
>>> chars[0]
65
>>> '%x' % chars[0]
'41'
>>> hex(chars[0])
'0x41'
>>> ['%x' % c for c in chars]
['41', '32']
>>> [hex(c) for c in chars]
['0x41', '0x32']
