Hello, Im back!

Firstly, Thank you @Dancergraham & @p1r4t3b0y trying to help me! I used youre hints & codes to make it. It took me quite long since Im begineer with python, but Im back here to share my first script which is finally working as intended! File attached at the end.

I know it is simple code but for me its a huge achievement

heres my coda:

looks like this:

previously looked like this mess:

This is how it WORKS:

**The reason of me sharing it is to get some ideas how to improve the script from you people. If you are interested to share some ideas please hit me up in PM or post in the comments.**

Next step is to connect it to the @karamba3d to make optimization with #galapagos. Should be easier part for me.

Dan.
