I am interested in taking in a single character,
我有兴趣接受一个角色,
c = 'c' # for example
hex_val_string = char_to_hex_string(c)
print hex_val_string
output:
输出:
63
What is the simplest way of going about this? Any predefined string library stuff?
这个最简单的方法是什么?任何预定义的字符串库?

There are several ways of doing this:
有几种方法可以做到这一点:
>>> hex(ord("c"))
'0x63'
>>> format(ord("c"), "x")
'63'
>>> "c".encode("hex")
'63'
To use the hex
encoding in Python 3, use
要在Python 3中使用十六进制编码,请使用
>>> codecs.encode(b"c", "hex")
b'63'

import binascii
x = b'test'
x = binascii.hexlify(x)
y = str(x,'ascii')
print(x) # Outputs b'74657374' (hex encoding of "test")
print(y) # Outputs 74657374
x_unhexed = binascii.unhexlify(x)
print(x_unhexed) # Outputs b'test'
x_ascii = str(x_unhexed,'ascii')
print(x_ascii) # Outputs test
This code contains examples for converting ASCII characters to and from hexadecimal. In your situation, the line you'd want to use is str(binascii.hexlify(c),'ascii')
.
此代码包含将ASCII字符转换为十六进制和从十六进制转换的示例。在你的情况下,你想要使用的行是str(binascii.hexlify(c),'ascii')。
