howe 1.0.4

Overview

The howe project contains the Howe class. A Howe object is similar to a zip object, except that all the iterators have to run out at the same time. Otherwise an ExceptionGroup (containing the StopIteration exceptions from the iterators that did run out) will be raised. The project is named for E. Howe, one of the intentors of the zipper.

Installation

To install howe, you can use pip. Open your terminal and run:

pip install howe

Implementation

class Howe:
    def __init__(self, *args):
        self._args = [iter(x) for x in args]

    def __iter__(self):
        return self

    def __next__(self):
        elements = list()
        errors = list()
        for arg in self._args:
            try:
                element = next(arg)
            except StopIteration as error:
                errors.append(error)
            else:
                elements.append(element)
        if not len(errors):
            return tuple(elements)
        if len(elements):
            raise ExceptionGroup("Howe failed.", errors)
        raise StopIteration
