Yeah, it can also become a catch all for all unnamed optional parameters.

>>> def get(url, *args, follow_redirects=False, headers=None):
...     print(f"u: {url}, a: {args}, f: {follow_redirects}, h: {headers}")
...
>>> get("https://dev.to")
u: https://dev.to, a: (), f: False, h: None
>>> get("https://dev.to", 1, 2, 3)
u: https://dev.to, a: (1, 2, 3), f: False, h: None
>>> get("https://dev.to", 1, 2, 3, follow_redirects=True, headers={"user-agent": "acme"})
u: https://dev.to, a: (1, 2, 3), f: True, h: {'user-agent': 'acme'}
>>> get("https://dev.to", follow_redirects=True, headers={"user-agent": "acme"})
u: https://dev.to, a: (), f: True, h: {'user-agent': 'acme'}
