class MyList(list): def __getitem__(self, n): return super().__getitem__(n-1) a = MyList(range(10)) print(a) print(a[4])

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: https://rszalski.github.io/magicmethods/#sequence But then again -- why would you? :)

You can use enumerate with a custom offset. Here, the first element is element 1: https://code.sololearn.com/cbH3QRT5RIzs/?ref=app You can also use this to make a list of 1-based tuples: print(list(enumerate(l, 1)))
