This is a calculator for functions like calculating GST, discounts, interest, unit conversions, time difference and much more! Feel free to use and modify as much as you like. This was mostly just a test project.
The files in the experimental folder are other small calculator experiments, some which don't work.
First, click on the main.py file to view the contents. Select all the text and copy it. Them, head to a Python compiler like https://www.online-python.com/ or https://www.programiz.com/python-programming/online-compiler/ and paste the code in there. The calculator is purely terminal based, just enter numbers when asked and click enter.
