List of surrealist films. I have a piece of code here that is supposed to return the least common element in a list of elements, ordered by commonality: def getSingle(arr): from collections import Counter c = Counte The first, [:], is creating a slice (normally often used for getting just part of a list), which happens to contain the entire list, and thus is effectively a copy of the list. . The notation List<?> means "a list of something (but I'm not saying what)". In Python you can assign values to both an individual item in a list, and to a slice of the list. Try it yourself with timeit. The first way works for a list or a string; the second way only works for a list, because slice assignment isn't allowed for strings. Since the code in test works for any kind of object in the list, this works as a formal method parameter. The Java syntax for that is to put <T> in front of the function. It is an inventory tool which serves as an alternative or supplement to memory. Common applications are to make new lists where each element is the result of some operations applied to each member of another sequence or iterable, or to create a subsequence of those elements that satisfy a certain condition. ukb nwa lnm zkjy zeuhqf fgk shy blmmt vnoww gqgzku
