Python File Header encoding statement

You can see this writing: #-*-coding: UTF-8-*-this is used to illustrate your Python source ProgramThe encoding used for the file. By default, your program needs to be written in ASCII code, but if you write Chinese in it, the python interpreter usually reports an error, but if you add the file encoding you use, python will automatically handle the error. However, I hate writing so long, because n declaration methods have to be recorded due to this encoding problem. For example, in HTML, in CSS files, how can this problem be solved,
The preceding format can also be written as follows:
# Coding = UTF-8
Or
# Coding: UTF-8

It's easy to remember, and the handwriting error rate is also reduced.
