Technology Quote by Mark Lutz
““Interestingly, the iteration protocol is even more pervasive in Python today than the examples so far have demonstrated — essentially everything in Python’s built-in toolset that scans an object from left to right is defined to use the iteration protocol on the subject object.””
About This Quote
Source Book: Learning Python, Mark Lutz, 1999
Python’s iteration protocol underlies most built‑in operations that traverse sequences from left to right.
In simple terms: Iteration drives most Python loops and scans.

Iterators can hide performance costs if misused.
![“Object-oriented programming aficionados think that everything is an object… this [isn't] so. There are things that are objects. Things that have state and change their state are objects. And then there are things that are not objects. A binary search is not an object. It is an algorithm” quote by Alexander Stepanov](https://sms4smile.com/quotes/img-quotes/ef9/alexander-stepanov-55292_algorithms_object-oriented-programming-aficionados_89704.jpg)
![“This description requires elaboration when the value and the slice being assigned overlap: L[2:5]=L[3:6], for instance, works fine because the value to be inserted is fetched before the deletion happens on the left.” quote by Mark Lutz](https://sms4smile.com/quotes/img-quotes/a52/mark-lutz-25814_quote_this-description-requires-elaboration-wh_1302432.jpg)
