1. Create a Python program that computes the median of a collections of numbers. The program should prompt the user to enter a comma separated list of numbers and then print the median.

2. What would the following snippet of Python code print if run?

   def edit(integer):
       integer = 0
   
   spam = 1
   edit(spam)
   print(spam)

3. What would the following snippet of Python code print if run?

   def edit(string):
       string = string + " zero"
   
   spam = "one"
   edit(spam)
   print(spam)

4. What would the following snippet of Python code print if run?

   def edit(a_list):
       a_list = a_list + [0]
   
   spam = [1, 2]
   edit(spam)
   print(spam)

5. What would the following snippet of Python code print if run?

   def edit(a_list):
       a_list.append(0)
   
   spam = [1, 2]
   edit(spam)
   print(spam)

6. What would the following snippet of Python code print if run?

   def edit(a_list):
       a_list.append(0)
   
   spam = (1, 2)
   edit(spam)
   print(spam)

7. What would the following snippet of Python code print if run?

   def edit(a_list):
       a_list = a_list + (0, -1)
   
   spam = (1, 2)
   edit(spam)
   print(spam)

8. What would the following snippet of Python code print if run?

   def edit(string):
       string.capitalize()
   
   spam = "one"
   edit(spam)
   print(spam)

9. What would the following snippet of Python code print if run?

   import turtle
   
   def edit(a_turtle):
       a_turtle.goto(1, 0)
   
   spam = turtle.Turtle()
   edit(spam)
   print(spam.position())

10. Create a Python function that takes a list of numbers and returns a new list that is equivalent to the normalization of the input array. A list is normalized by scaling and shifting all of the elements of a list such that the smallest value is 0.0 and the largest value is 1.0. Values in the list should maintain their relative differences. For example the list [25, 50, 75] would be normalized as the list [0.0, 0.5, 1.0].

11. Create a Python function that takes a list of numbers, normalizes the input list, and does not return anything.
