pytask is a workflow management system that facilitates reproducible data analyses. Its features include:

  • Automatic discovery of tasks.

  • Lazy evaluation. If a task, its dependencies, and its products have not changed, do not execute it.

  • Debug mode. Jump into the debugger if a task fails, get feedback quickly, and be more productive.

  • Repeat a task with different inputs. Loop over task functions to run the same task with different inputs.

  • Select tasks via expressions. Run only a subset of tasks with expressions and marker expressions.

  • Easily extensible with plugins. pytask is built on top of pluggy, a plugin management framework, which allows you to adjust pytask to your needs. Plugins are available for parallelization, LaTeX, R, and Stata, and more can be found here. Learn more about plugins in this tutorial.
