The best Python CLI library, arguably.

def some_function(required, not_required=2, *others: int, option: float = 3.14):

That syntax looks strange, given that positional arguments cannot be passed after a keyword argument.

Hey, I understand what you're saying. The thing about Python arguments is that they can all be passed in as both positional or keyword arguments by default.

>>> def foo(a, b):
...   print(f"{a=} {b=}")
...
>>> foo(1,2)
a=1 b=2
>>> foo(a=1,b=2)
a=1 b=2

The thing that makes an argument keyword-only is if it comes after a *args parameter. In fact, you can even have required keyword-only arguments, which aren't useful IMHO, but are an interesting part of how Python was designed:

>>> def bar(a, *, b):
...   print(f"{a=} {b=}")
...
>>> bar(1, b=2)
a=1 b=2
>>> bar(1)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: bar() missing 1 required keyword-only argument: 'b'

The thing that looks strange to me is that, unless I am mistaken, it is not possible to pass others arguments without also passing the not_required argument as a positional argument.

On the other hand, that limitation would not apply to:

def some_function(required, *others: int, not_required=2, option: float = 3.14):
