# `Otera.Iterable`
[🔗](https://github.com/georgeguimaraes/otera/blob/v0.1.0/lib/otera/iterable.ex#L1)

A Python iterable that is not a list or a tuple, with the behavior of its Python type.

`type` is the name of the Python type:

  * `"dict_keys"`, `"dict_values"` and `"dict_items"`, from the methods `keys()`, `values()` and `items()` of a dict. A view prints as `dict_keys([...])`, has a length, and is false when it is empty.
  * `"generator"`, from the filters `map`, `select`, `reject`, `selectattr`, `rejectattr`, `unique`, `items`, `batch` and `slice`, and the reverse iterators of the `reverse` filter, such as `"list_reverseiterator"`. An iterator is always true and has no length, so `x|select("odd")|length` raises like in Python.

A template iterates over these values like a list. Otera does not model the single pass of a Python iterator, so a template can iterate over a generator twice.

# `t`

```elixir
@type t() :: %Otera.Iterable{items: list(), type: String.t()}
```

# `view?`

```elixir
@spec view?(t()) :: boolean()
```

Returns true for the dict views, which have a length.
