You can do a lot of amazing things with Python. When I started teaching myself Python last year, one of the most interesting things I discovered was how relatively easy it was to create CLI apps. Since I learn best by doing, I went ahead to create norris-cli among other apps, and discovered the possibilities were endless 😄.
Building these kinds of projects is a great way to learn, and it's super fun. To improve my skills and help others learn, I'll be doing a whole series on "Building CLI Apps with Python". I'll start with the basics and go step by step. In the end, we'll put what we've learned into practice by creating a practice project*. Of course, what we'll make won't be very useful, but we'll learn enough in the process to go ahead and make something truly useful.
- Setting things up (Python 3.x, pip, Virtualenv, Click, etc)
- Commands, options & arguments
- Using Setuptools
- Prompting users for input
- CRUD (with an online API) (Practice project)
- Working with data structures
- Writing to local files
- Testing with pytest
- Posting a package on Pypi
I hope both the experienced and those just starting out with Python will find this series useful.
* I initially intended to do two practice projects but it seemed redundant so I settled on making the CRUD section the project.
