It should return a string with the letters of the word in the right places if they have been guessed, all in uppercase. If a letter has not been guessed, there should be a _ (an underscore) in that place.

## [PROBLEM 2]
# Write at least 3 return value tests and at least 4 side-effect tests for this class definition.
# At least one of your tests should apply to each method of the class.

# [PROBLEM 2]
## Grabbing data off the web
# (2) Put the request you made in problem 1 in a proper try/except clause.
# Then, use the .json() method on the response you get back to turn the data
# in one big Python dictionary. Save the Python dictionary in the variable
# airport_data.
## Write one line of code to create an instance of the photo class and store the instance in a variable my_photo.
my_photo = Photo('Photo1','Ansel Adams',['Nature', 'Mist', 'Mountain'])
## After you do that, my_photo.display_info() should produce the same string as the one stored in display_string.
# HINT: if you just call the constructor for the Photo class appropriately, everything will be taken care of for you. You just have to figure out, from the definition of the class, what to pass to the constructor. Remember the examples of creating a class instance from the textbook and from lecture/section!

# Write your three function calls below

#### 2. Define a function called mult_both whose input is two integers, whose default parameter values are the integers 3 and 4, and whose return value is the two input integers multiplied together.
def mult_both(x = 3, y = 4):
return x*y
print mult_both()

print "Testing whether your function works as expected (calling the function mult_both)"
test.testEqual(mult_both(), 12)
test.testEqual(mult_both(5,10), 50)
#### 3. Use a for loop to print the second element of each tuple in the list ``new_tuple_list``.
new_tuple_list = [(1,2),(4, "umbrella"),("chair","hello"),("soda",56.2)]
for (x, y) in new_tuple_list:
print y
#### 4. You can get data from Facebook that has nested structures which represent posts, or users, or various other types of things on Facebook. We won't put any of our actual Facebook group data on this textbook, because it's publicly available on the internet, but here's a structure that is almost exactly the same as the real thing, with fake data.
# Notice that the stuff in the variable ``fb_data`` is basically a big nested dictionary, with dictionaries and lists, strings and integers, inside it as keys and values. (Later in the course we'll learn how to get this kind of thing directly FROM facebook, and then it will be a bit more complicated and have real information from our Facebook group.)
# Follow the directions in the comments!
# first, look through the data structure saved in the variable fb_data to get a sense for it.
