Python出错问题,有没有大神给说说

Question

from Crypto.Cipher import AES
from binascii import b2a_hex, a2b_hex

class prpcrypt():
def init(self, key):
self.key = key
self.mode = AES.MODE_CBC

    # 加密函数，如果text不是16的倍数【加密文本text必须为16的倍数！】，那就补足为16的倍数

def encrypt(self, text):
    cryptor = AES.new(self.key, self.mode, self.key)
    text = text.encode("utf-8")
    # 这里密钥key 长度必须为16（AES-128）、24（AES-192）、或32（AES-256）Bytes 长度.目前AES-128足够用
    length = 16
    count = len(text)
    add = length - (count % length)
    text = text + (b'\0' * add)
    self.ciphertext = cryptor.encrypt(text)
    # 因为AES加密时候得到的字符串不一定是ascii字符集的，输出到终端或者保存时候可能存在问题
    # 所以这里统一把加密后的字符串转化为16进制字符串
    return b2a_hex(self.ciphertext).decode("ASCII")

    # 解密后，去掉补足的空格用strip() 去掉

def decrypt(self, text):
    cryptor = AES.new(self.key, self.mode, self.key)
    plain_text = cryptor.decrypt(a2b_hex(text))
    return plain_text.rstrip(b'\0').decode("utf-8")

if name == '__main__':
pc = prpcrypt('keyskeyskeyskeys') # 初始化密钥
e = pc.encrypt("my book is free")
d = pc.decrypt(e)
print(e, d)
e = pc.encrypt("我是一个粉刷匠")
d = pc.decrypt(e)
print(e, d)

这是源代码,
Traceback (most recent call last):

e = pc.encrypt("my book is free")

raise TypeError("Object type %s cannot be passed to C code" % type(data))
TypeError: Object type cannot be passed to C code
这是输出的错误信息,我用的Python34,请大神看看是什么错误 ,谢谢

Answer 1

提问的时候,最好能把问题描述清楚一些.
把代码贴出来,并指明TypeError是在哪一行发出的,大家才能很好的诊断问题.
只有一个TypeError,大家都不知道你给C代码传的是什么Python对象,不好解答.
还有,提问的时候,最好把Python的版本也一并指明
