There seems to be a mistake?

When i run card.py it happens a TypeError. Why is this?

line 33, in Card
PRIMES: list[int] = [2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41]
TypeError: 'type' object is not subscriptable

Thanks!

The lowercase list type hinting syntax was introduced in Python 3.9. Are you running a lower version of Python, and are you able to upgrade? It should work after you upgrade to 3.9 or later.

pip install treys==0.1.4 resolved this issue for me, having the package manager explicitly require 3.9+ for treys 0.1.5+ would help avoid these errors :)
