Serial: Sending data back and forth?

Projects Programming
1

Specs:
Arduino Uno R3
Raspberry Pi 3

I'd like to send data back and forth between these devices but I'm not sure how...

I already can send data from Arduino as text using Serial.print but this is just text as far as I know. Can someone tell me how to?

Text is what you want. See the tutorial Serial Input Basics.
