SyntaxError: invalid syntax

[fbartolom]

When I try to execute the script linking the library I get a syntax error:

Traceback (most recent call last):
File "remotenotifications.py", line 1, in
from apns2.client import APNsClient
File "/var/www/html/iPhone/tags/apns2/client.py", line 50
credentials: Union[Credentials, str],

This library requires at least Python 3.5. You're probably using an older version of Python.
