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.

word = ''.join(L) # this _strings_ the elements of L together. return word. Because most of the non-alphabetic characters we need to remove will be punctuation, the function is called dePunc. It uses a list comprehension that creates a list of all and only alphabetic characters (hence the if, which is allowed in list comprehensions).

The first line determines how many elements are in the list L and assigns the result to the variable n. The second line adds a new element to the list L with the value of x. The third line sorts the list L from smallest to largest (to get the reverse ordering, use the optional reverse argument, as in L.sort(reverse=True) instead).

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.

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.
