>>> a.update(\'         


        

Answer 1

Under the different versions of Python is different,I use Python 2.7,same as you write, it works well.

hashlib.md5(data) function, the type of data parameters should be 'bytes'.That is to say, we must put the type of data into bytes before hashes.

Requirements before the hash code conversion, because the same string have different values under different coding systems(utf8\gbk.....), in order to ensure not happen ambiguity has to be a dominant conversion.
