Making a set from dictionary values

I want to create a set from the values of an existing dict

def function(dictionary):
    ... 
    return set_of_values

Say my dictionary looks like this: {'1': 'Monday', '2': 'Tuesday', '3': 'Monday'}

I want a set returned that only contains the unique values, like this: 

{'Monday', 'Tuesday'}

For Python:

set(d.values())

Equivalent on Python 2.7:

set(d.viewvalues())

If you need a cross-compatible Python 2.7/3.x code:

{d[k] for k in d}

Just another way to unique out:

 >>> my_dict = {'1': 'Monday', '3': 'Monday', '2': 'Tuesday'}
 >>> {y:x for x,y in my_dict.iteritems()}.keys()
 ['Tuesday', 'Monday']
 >>>
