Add a function that finds whole words repeated next to other. For example, the the should be caught but not his history.
The md_files/sample.md example shown in this project already has one such issue.

The typos.py program hard codes the input directories and output filename. Modify the program to accept such data as CLI arguments. These arguments should also have a default value to make it easier to execute the program for similarly structured projects.
You can also use packages like Gooey to create a GUI from this CLI program.
Change the typos.py program so that it works for both plain text and Markdown input files based on filename extensions.
