1. Tutorial

This tutorial introduces python-dependency-resolver by means of example - we will walk through how to create a simple ordered todo list.

1.1. Getting started

Before we start, we have to install python-dependency-resolver.

$ python -m pip install python-dependency-resolver

We have to create a main.py file and import python-dependency-resolver.

Note

You can see our examples on Github

1.2. What do we have to do

My todo list is :

• Buying food

• Cooking

• Feeding kitties

• Feeding my self

• Doing the dishes

• Learning a new recipe

• Buying a cookbook

# main.py
from python_dependency_resolver import DependencyResolver

# [
#   my task: [requirements]
# ]
tree = {
    'Buying food': ['Learning a new recipe'],
    'Cooking': ['Buying food', 'Learning a new recipe'],
    'Feeding kitties': [],
    'Feeding my self': ['Cooking'],
    'Doing the dishes': ['Feeding my self', 'Feeding kitties'],
    'Learning a new recipe': ['Buying a cookbook'],
    'Buying a cookbook': []
}

dependency_resolver = DependencyResolver()
result, unsolved = dependency_resolver.resolve(tree)
# [['Buying a cookbook', 'Learning a new recipe', 'Buying food', 'Cooking', 'Feeding kitties', 'Feeding my self', 'Doing the dishes'], []]
