1. Write a function called swap that takes as input a dictionary and returns a new dictionary where key is the old value and the value is the old key, i.e swaps the key/values.  You may assume that the value are unique.

>>> d = {"a":1, "b":2, "c":3}
>>> swap(d)
{1: 'a', 2: 'b', 3: 'c'}

2. Write a function called capitalized_lines that takes as input a file and counts the number of lines that start with a capital letter.

3. T/F: If we ran the following code, 10 would be printed:

def mystery(x):
    x = 2
    
x = 10
mystery(x)
print(x)

4. Rewrite the following function to improve the style:

def longwinded(a, b, c):
    if a > b:
        if a > c:
            return True
        else:
            return False
    else:
        return False

5. Write a function that takes two parameters: a dictionary and a number.  The function should add the number to each value in the dictionary.

6. Write a function that takes a string as a parameter and returns the string with all the uppercase letters removed.  Hint, the isupper method may be useful.
