TypeError: 'staticmethod' object is not callable

I followed the instructions and installed ryanair-py on Python version 3.8.10 (Ubuntu Linux installation)
I tried running the code in the documentation, but I get the following error:

>>> flights = api.get_cheapest_flights("DUB", tomorrow, tomorrow + timedelta(days=1))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/luca/.local/lib/python3.8/site-packages/ryanair/ryanair.py", line 76, in get_cheapest_flights
    response = self._retryable_query(query_url, params)["fares"]
  File "/home/luca/.local/lib/python3.8/site-packages/backoff/_sync.py", line 92, in retry
    wait = _init_wait_gen(wait_gen, wait_gen_kwargs)
  File "/home/luca/.local/lib/python3.8/site-packages/backoff/_common.py", line 29, in _init_wait_gen
    initialized = wait_gen(**kwargs)
TypeError: 'staticmethod' object is not callable

Thanks in advance

same error here, using debian and MX(debian based),
$ python3 --version
Python 3.9.2
getting:

Thanks for the reports all, a bug may have been introduced in my last refactor, I'll take a look as soon as I get the time.

Acctually downgrading works, so its a way to have it working for time being.
pip3 install ryanair-py==2.3.1

I suspect what's happening here is my most recent changes aren't compatible with python < 3.10.

Namely, from documentation https://docs.python.org/3/library/functions.html#staticmethod :

Changed in version 3.10: Static methods now inherit the method attributes (module, name, qualname, doc and annotations), have a new wrapped attribute, and are now callable as regular functions.

Python 3.9 isn't EOL until ~the end of 2025, so I will try to fix this at some point.

However, if easy for you, you can just switch to using python >= 3.10 for now :)

The issue is still happening

[cohaolain]

Yes, I still haven't gotten around to fixing this on python < 3.10.

To avoid this issue, please use python >= 3.10 for now if you can, or use the previous version of this library ryanair-py==2.3.1.
