One way to leverage on your loops and show that your loops correctly give the desired result is to prove your loops with loop invariants.   What is a loop invariant A loop invariant is a proof 0http://emekadavid-solvingit.blogspot.com/2020/09/check-if-python-list-contains-unique.htmlabstractioncodingpython programmingnoreply@blogger.com (Emekadavid)Sat, 19 Sep 2020 15:55:00 +0100tag:blogger.com,1999:blog-5022641238027681605.post-4843737697215854601While going through a Reddit group post on python recently, I saw a question that was similar to the element uniqueness problem and the way the answer was formulated struck me as odd. I thought the implementation was not optimal or efficient, so I volunteered an answer that I knew was better.   The question was: how do I check to see if my python list contains elements or items that are 0http://emekadavid-solvingit.blogspot.com/2020/09/emulating-lists-in-your-python-classes.htmlabstractioncodingpython programmingnoreply@blogger.com (Emekadavid)Thu, 17 Sep 2020 14:27:00 +0100tag:blogger.com,1999:blog-5022641238027681605.post-6947322162909633238Python provides for ways we can emulate the native data structures in our own defined classes. In this post, I will show you one way you can emulate a list. A list is a mutable sequence that has items which are ordered by index.   In my post on operator overloading and dunder methods, I showed you a way a class can behave like a list. But we can extend that concept a little further by 1
