Invalid syntax on python match function

I'm extremely confused about this error. All I'm trying to do is use the match function but I keep getting a syntax error even though I believe there's nothing wrong with this.

Here's my code:

def compile(code):
    code_ptr = 0;
    mem_ptr = 0;
    memory = [0] * 1000
    loop = []

    while code_ptr > len(code):
        command = code[code_ptr]
        match command:
            case '>':
                mem_ptr += 1
            case '<':
                mem_ptr -= 1
            case: '+':
                memory[mem_ptr] + 1
            case '-':
                memory[mem_ptr] - 1
        code_ptr += 1

    print(memory)

Here's the error:

    match command:
          ^
SyntaxError: invalid syntax

I'm running Python 3.8.5

As mentioned in the comments, the match syntax is only available as of Python 3.10. There are no from __future__ tricks or backports to make it work; it's a significant syntax change. So unfortunately the only way to get this syntax is to upgrade your Python version.
