# mulpyplexer — A module that multiplexes interactions with lists of python objects.

License: permissive · Maintenance: abandoned · Downloads: 171.8K/mo

## What it is and what it does

Mulpyplexer wraps a list of Python objects in a multiplexer that broadcasts method calls and attribute access across all items, collecting results into a new multiplexed object. When you call a method on the multiplexer, it invokes that method on each wrapped object and returns a new multiplexer containing the results; similarly, accessing an attribute returns a multiplexer over the attribute values from each item.

The package has no runtime dependencies and is purely a syntactic convenience layer. It is designed for scenarios where you want to apply the same operation uniformly across a collection of objects without explicit looping, though the same effect can typically be achieved with list comprehensions or map().

Use it for:

- Apply the same method to multiple object instances and collect results without writing a loop.
- Chain operations across a collection: call methods on results, then access attributes, all in one expression.
- Prototype or explore object behavior when working interactively with lists of similar objects.
- Simplify code that repeatedly applies identical transformations to each item in a heterogeneous collection.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Mulpyplexer applies method calls and attribute access to lists of Python objects in parallel, returning a new multiplexed object containing the results from each item in the list.

No. The package is abandoned (last release 2021-01-11, 2041 days old), has high install friction (source-only distribution), and offers no advantage over built-in Python idioms like list comprehensions or map(). Unless you are maintaining legacy code that already depends on it, use standard Python iteration patterns instead.

## Install

pip install mulpyplexer
uv add mulpyplexer
poetry add mulpyplexer

## Installing mulpyplexer

Before you install: High install friction: the package is abandoned (last release 2021-01-11, no commits tracked), has no runtime dependencies to ease setup, and ships as a source tarball with no wheel distribution.

License in practice: BSD permissive license allows commercial and private use with minimal restrictions, typical of mature open-source libraries.

Quickstart:

import mulpyplexer

class A:
    def add(self, j):
        return A(self.value + j)

one = mulpyplexer.MP([A(), A(), A()])
two = one.add(5)
result = two.mp_items

Package is abandoned and may not build or run on Python versions released after 2021; no wheel distribution available.

Verify before relying:

- Whether the package works with current Python versions (python_support unspecified, requires_python empty)
- Whether the source tarball builds without compilation errors on modern systems
