A simple library to run one task, or multiples ones in sequence or parallel

Project description


Simple tasks runner for Python.

This can be helpful to handle automated processes and make them available via command line interface via click.



import click
from simpletasks import Cli, CliParams, Task
def cli():

@Cli(cli, params=[click.argument("n", type=int), CliParams.progress()])
class FibonacciTask(Task):
    def compute(self, n: int) -> int:
        self.logger.debug(f"Called with n={n}")
        f1, f2 = 0, 1
        if n == 0:
            return f1
        if n == 1:
            return f2
        for _ in self.progress(range(1, n)):
            f1, f2 = f2, f1 + f2
        return f2

    def do(self) -> None:
        n = cast(int, self.options.get("n"))
        result = self.compute(n)
        print(f"f({n}) = {result}")

if __name__ == "__main__":


$ python sample/ fibonacci 3 --no-progress
f(3) = 2


To initialize the environment:

poetry install --no-root
poetry install -E click -E tqdm

To run tests (including linting and code formatting checks), please run:

poetry run pytest --mypy --flake8 && poetry run black --check .
