Some problems encountered in the process of Python encoding in Chinese

First, make clear the difference between encode () and Decode ()

The role of Encode () is to convert Unicode-encoded strings to other encoding formats.

For example: St1.encode ("Utf-8") is the function of encoding Unicode encoded ST1 into a utf-8 encoded string

The role of Decode () is to convert strings from other encoded formats into Unicode-encoded strings.

For example: St2.decode ("Utf-8") is the function of decoding UTF-8 encoded string ST2 into a Unicode encoded string

Second, in addition to Unicode-encoded strings, no matter what kind of encoded string you want to convert to another encoding format, you must first decode and then encode

Non-Unicode encoding--Unicode---Non-Unicode encoding

Like what. The UTF-8 encoded string St wants to be converted to a GBK encoded string. You must go through the following steps:

St=st.decode ("Utf-8")#解码为Unicode编码

St=st.encode ("GBK") #从Unicode编码编码为gbk编码

Third. We often use the Utf-8 code is also divided into a BOM and no BOM.

IV: About the Chinese encoding of the JSON file.

Using Python to read JSON files is often used to the json.load () function, which is required for the format of the JSON file

1) JSON file is utf-8 without BOM encoded, then can directly use the json.load (filename) function to read the contents of the JSON file

2) The JSON file is encoded with the Utf-8 with BOM and cannot be read with the Json.load () function. Json.load () does not correctly identify

3) JSON file when other encoding, for example GBK, to the JSON file encoding format as a parameter to Json.load ():

eg. Json.load (filename, "GBK")

Five, how to view and set their own file encoding it?

Introduce a personal favorite tool "nodtepad++", any software tube home with a button installed.

With this tool you can easily view the current encoding of your files. and can easily be converted into arbitrary other coding formats
