review chapter 3

[rioj7]

• don't call your variables list, list is a build in type and you loose the constructor
• in bubble sort add a test if done a swap in a pass, if not => data is sorted
• no need to return the list because a list is a mutable data structure, make a copy of the list (data[:]) if needed to have different sorted list
• in insertion sort test for (j >= 0) before testing value in list, -1 is a valid list index
