What are the commonly used codes in Pytho? for this problem, this article introduces the corresponding analysis and solutions in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

1 、 ASCII

ASCII code uses one byte encoding, so its range is basically only English letters, numbers and some special symbols, only 256characters.

2 、 Unicode

Commonly known as universal code, all languages are unified into one code. The limitation of ascii code and the problem of garbled code are solved.

Unicode codes generally use two bytes to represent a character, and especially obscure ones use four bytes to represent a character.

3 、 UTF-8

A new problem arises. If it is unified into unicode coding, the problem of garbled code will disappear. But if the text you write is basically in English, Unicode coding requires twice as much storage space as ascii coding, which is very inconvenient for storage and transmission.

Utf-8 application, it is a "variable length encoding", if it is an English character, it uses ascii encoding, occupies one byte. If it is a commonly used Chinese character, it will take up three bytes, and if it is an obscure character, it will take up 40.6 bytes.

4 、 GBK

GBK is only used to encode Chinese characters, GBK full name "Chinese character internal code extension specification", using double-byte coding.

After introducing the above four, paste a comparison of five common codes below to get a more intuitive understanding of the differences between these codes.

This is the answer to the commonly used coding questions in Pytho. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel to learn more about it.
