Key Concepts Explanation

Key Concept 1

In Python collections like lists and sets, the in operator is used to check if a specific element exists in the collection. For example:

l = [1, 2, 3, 4]  # list
1 in l
5 in l

Key Concept 2

The len function is utilized to determine the number of elements present in a collection. Additionally, the sorted function can be employed to sort the elements within the collection without altering the original data. For instance:

l = [1, 2, 3, 4]  # list
