match python 3.9.1 invalid syntax error?

Question

Python

Python 3.9.1

What is the correct way to use match?

All examples on the Internet do not want to work correctly.
Gives all the time:

^
SyntaxError: invalid syntax

An example of another code from the Internet:

quit_flag = False
match quit_flag:
    case True:
        print("Quitting")
        exit()
    case False:
        print("System is on") 
}

How to decide? Google is silent.

Answer 1

Ask Google in which version the match-case appeared, I think it will not be silent. It's 3.10
