Am I missing something with Python not having interfaces?

[jmDesktop]

Studying OOP and noticed that Python does not have Interfaces.  Is
that correct?  Is my schooling for nought on these OOP concepts if I
use Python.  Am I losing something if I don't use the "typical" oop
constructs found in other languages (Java, C# come to mind.)  I'm
afraid that if I never use them I'll lose them and when I need them
for something beside Python, I'll be lost.  Thank you.
