Encode (), decode () character encoding issues

Python3, changed the default encoding, changed in order to Unicode

Prerequisite Knowledge:

1. Utf-8 relationship to Unicode: Https://baike.baidu.com/item/UTF-8/481798?fr=aladdin
2. The \x represents the hexadecimal data.
3. Encode default is Utf-8, the right figure in the \x corresponding to the Unicode to UTF-8 encoded data:
4. UTF-8: Use 1, 2, 3, 4 bytes for all characters, a priority of 1 characters, not enough to increase one byte, up to 4 bytes. English accounts for 1 bytes, European languages accounted for 2, East Asia accounted for 3, other and special characters accounted for 4
5. Unicode has a large capacity, and almost all other encodings have mappings on them, such as the Chinese encoding method GBK
6. , so the ' medium ' encoding in Unicode is 20013

Python3 STR is Unicode, used in binary, 16, and other formats bytes

Decode is to tell Unicode what you are coding:

The result of encode is a bytes object: a hexadecimal representation of the corresponding character's various encoding methods

The following is the result of encode in GBK format:

So the decode and encode are actually:
