解决方案 如果你只是简单的解码或编码一个十六进制的原始字符串,可以使用 binascii 模块。...例如: >>> s = b'hello'>>> import binascii>>> h = binascii.b2a_hex(s)>>> hb'68656c6c6f'>>> binascii.a2b_hex...函数 base64.b16decode() 和 base64.b16encode() 只能操作大写形式的十六进制字母 而 binascii 模块中的函数大小写都能处理。
Initial byte string s = b'hello' Encode as hex import binascii h = binascii.b2a_hex(s) h b...'68656c6c6f' Decode back to bytes binascii.a2b_hex(h) b'hello' or import base64 h = base64
