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. The Java syntax for that is to put <T> in front of the function. This is exactly analogous to declaring formal parameter If you declare a variable named list in your module's global namespace, the interpreter will never search for that name in a higher-level namespace (that is __builtins__). This is exactly analogous to declaring formal parameter Jan 12, 2009 · A List uses an internal array to handle its data, and automatically resizes the array when adding more elements to the List than its current capacity, which makes it more easy to use than an array, where you need to know the capacity beforehand. Nov 2, 2010 · When reading, list is a reference to the original list, and list[:] shallow-copies the list. The second, list(), is using the actual list type constructor to create a new list which has contents equal to the first list. Try it yourself with timeit. This will give you a list starting at index a (inclusive) and ending at index b (exclusive) picking elements at a step of c. 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. repeat (). The notation List<?> means "a list of something (but I'm not saying what)". Since the code in test works for any kind of object in the list, this works as a formal method parameter. Using a type parameter (like in your point 3), requires that the type parameter be declared. For example, 17 is element 2 in list 0, which is list1[0][2]: Nov 2, 2010 · When reading, list is a reference to the original list, and list[:] shallow-copies the list. Feb 25, 2015 · A list of lists would essentially represent a tree structure, where each branch would constitute the same type as its parent, and its leaf nodes would represent values. When assigning, list (re)binds the name and list[:] slice-assigns, replacing what was previously in the list. For example, 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.

Other than that I think the only difference is speed: it looks like it's a little faster the first way. Point to the item you want to move. Jan 27, 2012 · list[a:b:c], a is the starting index, b is the ending index and c is the optional step size. timeit () or preferably timeit. 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 I'm looking for a quick way to create a list of values in C#. Drag the item where you want.
