A list in Python is created by enclosing its elements in brackets: Elements in a list are accessed the same way elements are accessed in tuples. Special lists: ranges. Often the lists we use have a simple structure: the numbers from 0 to 9, or the numbers from 10 to 20.

If no element in the list satisfies the predicate procedure, findlast. should produce . null (in Scheme) or . None (in Python). For full credit, your procedure’s running time should be in O(n) where n is the number of elements in the input list. For example, Python: >>> def iseven(n): return n%2 == 0 >>> findlast([1,2,3], iseven)

By now we know that Python likes to start counting with zero 0 as the “first” item as we have seen previously with range() for example. In the same way, items in the list are indexed starting with zero 0; the last item is referenced as -1.

In Python, arrays are native objects called lists. List index starts at 0 (unlike Raptor). The following is a method used when you know the elements of the array. even_numbers = [2, 4, 6, 8, 10] You can use the print statement to display an entire list, as shown here: print even_numbers

A list is like a record in Ada (any number of any types can be put in), and a tuple is like a list, only once it has been declared it cannot be changed. One exciting feature of Python is that all the sequence types support slicing. This means that a colon can be used in the subscript to denote which elements of the sequence are to be selected.
