DeepSource issue: Implicit enumerate calls found

Using `range(len(...))` is not pythonic. Python does not have not
index-based loops. Instead, it uses collection iterators.

Python has a built-in method enumerate which adds a counter to an
iterable. Using this, you can access the counter and the value from
the iterable at the same time. It is therefore recommended to replace
`range(len(...))` with `enumerate(...)`.
