Problem calling attributes containing '-'

[mohanex]

Hello,

I have been using the Munch library for a while now.
On my python code, I imported some parametrs from an YAML file and then tried to iterate on them one by one. The problem is that some parametrs with the '-' caracter are not accepted and my python 3.11.7 throws :

Traceback (most recent call last):
  File "PATH\venv\Lib\site-packages\munch\__init__.py", line 116, in __getattr__
    return object.__getattribute__(self, k)
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
AttributeError: 'Munch' object has no attribute 'llm'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "PATH\venv\Lib\site-packages\munch\__init__.py", line 119, in __getattr__
    return self[k]
KeyError: 'llm'

My key is llm-api but the Munch object does just recongnize llm and not the rest of the key.
Is this a common problem?

PS : I resolved this issue by replacing '-' to '_' on my YAML file and it works perfectly, otherways I just want to report this because it made me crazy for some hours and also to help some beautiful lost soul in the future.
