Make sure that you have python 3.7.x installed. Some functionality (like type-hints\n   and f-strings) from later versions of python are used, so you should  make sure that\n   you have the correct version.\n2. Run `conda env create -f environment.yml` to make sure that you have installed the\n   necessary dependencies.\n\n# How to use\nFor each task you'll find the description at the beginning of the file,\nbut there are also other useful information on the task function docstring.\nThe tasks are marked with a difficulty ranging from 0-5, where 0 should be very easy, while 5\ncan be quite difficult.\nSome tests will also have timeouts.\n\nTo run tests, simply run `pytest tests` from the project root.\nThe tasks that are not implemented are skipped so they'll not invalidate the other tests.\n\nThe _solutions_ folder contains my solutions for some of the tasks.\nThey're not intended to be the best solutions at all.\nIf you want to propose a solution, it'll be more than welcome.\n\n# Tasks\nHere is a list of the tasks:\n\n|   | Name              | Difficulty | Solution |\n|---|-------------------|------------|----------|\n| 1 | _exact_ _hours_   | 3          |          |\n| 2 | _lisp_            | 2          | [x]      |\n| 3 | _matmul_          | 4          |          |\n| 4 | _pipes_           | 4          |          |\n| 5 | _training_        | 5          |          |\n| 6 | _wifi_ _password_ | 1          | [x]      |\n| 7 | _signal_ _crossing_ | 3        | [x]      |\n| 8 | _marketing_       | 1          | [x]      |\n\n# License\n[![License: MIT](https://img.shields.io/badge/License-MIT-yellow.svg)](https://opensource.org/licenses/MIT)","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmromanelli9%2Fpython-programming-challenges","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmromanelli9%2Fpython-programming-challenges","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmromanelli9%2Fpython-programming-challenges/lists"}
