Encoding and decoding in Python3

#一个知识点是: There are two types of string data in Python3, str type and bytes type, sty type stores unicode data, Bytes type stores bytes data

#当我们在word上编辑文件的时候, the data is stored in memory in Unicode form before it is saved.
#当我们点击保存时, the data will be encoded by the editor (such as UTF-8, GBK) encoding bytes byte string stored on the hard disk, the advantage is to save storage space------encode
#当我们又重新打开文件时, Word also places these bytes byte-string decoding city Unicode forms in memory, and the data is presented to us in clear text---------decode
