The first time I got into dealing with data in Python was when Noah gave me a cool idea to try out on my own: “you should write a tool to find duplicates”. We were both working at a media agency that had a large shared storage server. Finding duplicates was a neat idea to ...

SetsFast lookups without duplicatesIdeal for situations where uniqueness is crucial, and fast membership testing is required. DictionariesKey-value lookups (faster than lists)Perfect for mapping keys to values, offering fast access times and efficient insertion and deletion operations. ...
Every element is unique (no duplicates) and must be immutable (which cannot be changed). However, the set itself is mutable. We can add or remove items from it. And since set is unordered, you can’t do indexed operations on sets. set.add(element) –Adds the element to the set. ...
The probability of finding duplicates in a given set is extremely low. Even with a trillion UUIDs, the probability of a duplicate existing is much, much less than one-in-a-billion. 在给定集合中找到重复项的可能性非常低。 即使拥有一万亿个UUID,重复存在的可能性也远远小于十亿分之一。
Once we've gone through all the rule lines, we use the set function to consolidate all the duplicates in our list into a single list of unique elements. Finally, our return function gives that information back to the calling code. But not all functions have to have a return value. Now ...
