  We have seen several examples of lists in Python. Sounds are lists of sample objects. Pictures are lists containing lists of pixel objects. When we use a for loop, we iterate over a list of items. We have typically used lists of pixels, lists of samples, or lists of integers within a certain range in our ...

  Iterating Over Lists (Sequences) Python’s for statement provides a convenient means of iterating over lists (and other sequences). In this section, you will explore both for loops and while loops for list iteration. For Loops A for statement is an iterative control statement that iterates once for each element in a specified sequence of elements.

  Python supports iterating directly over the items of a list using the for statement. Listing 2 shows a Python program that computes the same summation of the list discussed in the previous problem. Instead of using indexing, this program iterate over the items of the list vals2 and the nal result is the same as in the previous program.
