PyQt6 Dynamic Programming

This demo program shows how to update a python file and reload it to update the running program without restarting the whole python app.

The output:

The code:

inputs.py:

1 2 3

A = 1.6 B = 7.5 C = 1.5

main.py:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63
