+Lab 00: Average Numbers
 
+We're going to average a list of numbers. Start with the following list, iterate through it, keeping a 'running sum', then divide that sum by the number of elements in that list. Remember len will give you the length of a list.
+
+The code below shows how to loop through an array, and prints the elements one at a time.
+
+nums = [5, 0, 8, 3, 4, 1, 6]
+
+# loop over the elements
+for num in nums:
+    print(num)
+
+# loop over the indices
+for i in range(len(nums)):
+    print(nums[i])
+
+Version 2
+
+Ask the user to enter the numbers one at a time, putting them into a list. If the user enters 'done', then calculate and display the average. The following code demonstrates how to add an element to the end of a list.
+
+nums = []
+nums.append(5)
+print(nums)
+
+Below is an example input/output:
+
+> enter a number, or 'done': 5
+> enter a number, or 'done': 3
+> enter a number, or 'done': 4
+> enter a number, or 'done': done
+average: 4
