Methods to identify whether it's Amphoteric, basic or acidic

How do you know whether a compound is amphoteric, basic, or acidic? Are there any methods?

You can identify if a molecule is basic if it accepts a proton (H+) and if it is acidic it will lose/donate one of its protons. On the other hand, it can be amphoteric if it can both accept and donate a proton. So, H2O is amphoteric because it can accept a proton to become H3O+ or it can lose a proton to become OH-
