In this video we’ll create a standalone .exe file for our Calculator app with Kivy and Python. We’ll be using the free pyinstaller to do all of this work.
Step One: pip install pyinstaller
Step Two: pyinstaller calc.py -w
Step Three: modify our calc.spec file, making several changes shown in the video.
Step Four: pyinstaller calc.spec -y
Step Five: Zip up all the files into one .zip file that you can share!
Python Code: calc.spec
