def __getitem__(self, n):
return super().__getitem__(n-1)

No .Python list start from 0th index.

I guess you can build your own class on top of the regular list and just overwrite the magic methods related to indexing. Take a look in here:

But then again -- why would you? :)

You can use enumerate with a custom offset. Here, the first element is element 1:

You can also use this to make a list of 1-based tuples:
print(list(enumerate(l, 1)))
