Example given not working

[nizamsp]

Example given in the readme is not working. Am I doing something wrong?

import xxtea
text = "Hello World! 你好，中国！"
key = "1234567890"
encrypt_data = xxtea.encrypt(text, key)
decrypt_data = xxtea.decrypt(encrypt_data, key)
print(text == decrypt_data);

ValueError: Need a 16-byte key.
