访问set集合元素 由于集合中的元素是无序的,因此无法向列表那样使用下标访问元素。访问集合元素最常用的方法是使用循环结构,将集合中的数据逐一读取出来。 DeletesetLikeother sequencetype.Wecan usedel()todeleteset as well.del(set1)OperationsofSet1.AddElementToadd elementstotheset collection,we can use thead...

You can use the .cache_info() method to see how the cache performs, and you can tune it if needed. In your example, you used an artificially small maxsize to see the effect of elements being removed from the cache: Python >>> fibonacci(10) Calculated fibonacci(1) = 1 Calculated fi...
How to add elements to a Python list? Unlike tuples and strings,lists in Python are “mutable”, that is, mutable data structures. We can add elements to aPython list, remove elements, and change their order. There are several approaches to this, each with its own advantages and disadvant...
