如何在Python中将单个字符转换为其十六进制ASCII值? [英] How do I convert a single character into its hex ASCII value in Python?

问题描述

我有兴趣录入一个字符.

I am interested in taking in a single character.

c = 'c' # for example
hex_val_string = char_to_hex_string(c)
print hex_val_string

输出:

63

最简单的方法是什么?有预定义的字符串库的东西吗?

What is the simplest way of going about this? Any predefined string library stuff?

推荐答案

有几种方法可以做到这一点:

There are several ways of doing this:

>>> hex(ord("c"))
'0x63'
>>> format(ord("c"), "x")
'63'
>>> import codecs
>>> codecs.encode(b"c", "hex")
b'63'

在Python 2上，您还可以使用 hex编码像这样(不适用于Python 3 +):

On Python 2, you can also use the hex encoding like this (doesn't work on Python 3+):

>>> "c".encode("hex")
'63'
