window_padded

emlib.iterlib.window_padded(seq, size=3, step=1, paddingval=None)[source]

Similar to window, but the last window will be padded

Parameters:

  • seq (Iterable[TypeVar(T)]) – the sequence

  • size – the size of each window

  • step – how much to advance the window each iteration

  • paddingval – value used to pad the last iteration if there are not enough items

Return type:

Iterator[tuple[TypeVar(T), ...]]

Returns:

an iterator of tuples, where each tuple has size elements

Example

>>> list(windowed([1, 2, 3, 4, 5, 6], 3, 2))
[(1, 2, 3), (3, 4, 5), (5, None, None)]
