Traverse a Python iterator or generator

iterate(it, f = base::identity, simplify = TRUE)

iter_next(it, completed = NULL)

as_iterator(x)

## Arguments

it Python iterator or generator Function to apply to each item. By default applies the identity function which just reflects back the value of the item. Should the result be simplified to a vector if possible? Sentinel value to return from iter_next() if the iteration completes (defaults to NULL but can be any R value you specify). Python iterator or iterable

## Value

For iterate(), A list or vector containing the results of calling f on each item in x (invisibly); For iter_next(), the next value in the iteration (or the sentinel completed value if the iteration is complete).

## Details

Simplification is only attempted all elements are length 1 vectors of type "character", "complex", "double", "integer", or "logical".
