Project party wednesday 9/28 6:30-8:30pm in 247 cory hall. The midterm 1 exam and solutions are posted. Built-in data type in python that"s used pretty much everywhere. Lists can be initialized as odds = [41, 43, 47, 49] Selection of elements by index digits[i] getitem(digits, i) [2, 7] + digits * 2 add([2, 7], mul(digits, 2)) Nested lists pairs = [[10, 20], [30, 40]] Built-in operators for testing whether an element appears in a compound value digits = [1, 8, 2, 8] [1, 2] in [3, [1, 2], 4] => true. [1, 2] in [3, [[1, 2]], 4] => false. For statements reduce the amount of code necessary to traverse through the list.
