luisy is a Python framework that extends luigi and further simplifies building data science pipelines by reducing development complexity. Thus, it makes LUI**gi more ea**SY.

An example pipeline

This is how an end-to-end luisy pipeline may look like:

import luisy
import pandas as pd

class InputFile(luisy.ExternalTask):
    label = luisy.Parameter()

    def get_file_name(self):
        return f"file_{self.label}"

class ProcessedFile(luisy.Task):
    def run(self):
        df = self.input().read()
        # Some more preprocessings
        # ...
        # Write to disk
class MergedFile(luisy.ConcatenationTask):
    def requires(self):
        for label in ['a', 'b', 'c', 'd']:
            yield ProcessedFile(label=label)
