Input and Output Programming

[Ducats]

Thanks for letting me join your forum. I am trying to create a simple PLC style controller with Raspberry pi and Python software. I'm very new to programming and looking for direction to start my research? I have done decent amount of searching with no success. My issues is most likely searching the wrong thing.

My project is to create a differential temperature controller for 5 sets of pumps in my water solar system, using 8 temperature inputs.

Thanks for any input.
