A quick, dirty implementation of the Dale Chall readability test for Python 2 and Python 3. This test uses data from the Dale Chall Familiar words list and the Scrabble Tournament words list to determine the difficulty of a word.

• Python 2.7 or Python 3 (most macOS and Linux computers come with Python preinstalled, but Python 3 is recommended)

First, download this archive or clone the repository from GitHub:

git clone https://github.com/alicerunsonfedora/dalechall

In the Terminal, run dale.py from the folder with the following arguments:

• -i/--input: (Required) The text file containing the sample you want to analyze.

Optionally, if you want to have all of the statistics and data in a separate file:

• -e/--export-data: The path to where you want the script to export the statistical data/words to as a JSON file.
