List Characteristics. Lists are: Ordered - They maintain the order of elements.

Python's *for* and *in* constructs are extremely useful, and the first use of them we'll see is with lists. The *for* construct -- for var in list -- is an easy way to look at each element in a list (or other collection). Do not add or remove from the list during iteration. squares = [1, 4, 9, 16] sum = 0. for num in squares: sum += num.Consider a Python list, in order to access a range of elements in a list, you need to slice a list. One way to do this is to use the simple slicing operator i.e. colon (:). With this operator, one can specify where to start the slicing, where to end, and specify the step. List slicing returns a new list from the existing list.Programming can seem daunting for beginners, but the best way to get started is to dive right in and start writing code.
