Could it be faster? Space. Does the program use a reasonable amount of memory, or is it unnecessarily taxing system resources? Elegance. Does the program represent an elegant solution to the problem, or does it feel like a maze with no exit? Courses in data structures and algorithm analysis explore these questions in more depth. Debugging As programs become more complicated, it also becomes more difficult to analyze their behavior, particularly when problems arise. Debugging is the art of finding and removing errors or bugs in programs.

End just before stop. =⇒ Caution: These are not intuitive at first. Ranges start at 0 unless you specify otherwise, and they end before the stopping point you provide. Repetition: For Loops 21 To see the elements that a range() will iterate over, you can use the list() type converter: list(x) Convert x to a list. For example, list(range(4)) = [0, 1, list(range(2, 4)) = [2, list(range(2, 10, 3)) = list(range(5, 2, -1)) = 2, 3] 3] [2, 5, 8] [5, 4, 3] Notice that with a step size of −1, the sequence still stops one before the stop we provided.

Explain why or why not. 1 to answer these questions: (a) Describe the effect of removing the if statement (and its body) at line 14. Explain the result. Hint: an easy way to do this is to put comment symbols at the beginning of those two lines, thereby changing the code into comments. This is called commenting out a section of code. (b) Describe the effect of removing the if statement (and its body) at line 16. Explain the result. (c) Describe the effect of removing the if statement (and its body) at line 18.
