1.
Write a function called get_counts that takes an iterable object (e.g. a list) as a 
parameter and counts how many times each item occurs in the sequence and returns a dict 
where the keys are the items and the values are the number of times the item occured.

For example,

>>> get_counts([1, 1, 2, 3, 1, 2, 5, 5])
{1: 3, 2: 2, 3: 1, 5: 2}
>>> get_counts("an apple and banana")
{'a': 6, ' ': 3, 'b': 1, 'e': 1, 'd': 1, 'l': 1, 'n': 4, 'p': 2}

2.
Now, right a function called print_counts that takes a dictionary as a parameter
and prints the data out as key [tab] value.  You may need to look at the book
to see how to iterate over a dictionary.

>>> print_counts(get_counts([1, 1, 2, 3, 1, 2, 5, 5]))
1	3
2	2
3	1
5	2
>>> print_counts(get_counts("an apple and banana"))
a	6
 	3
b	1
e	1
d	1
l	1
n	4
p	2
