Python dictionary: Get list of values for list of keys

Is there a built-in/quick way to use a list of keys to a dictionary to get a list of corresponding items?

For instance I have:

>>> mydict = {'one': 1, 'two': 2, 'three': 3}
>>> mykeys = ['three', 'one']


How can I use
mykeys
to get the corresponding values in the dictionary as a list?

>>> mydict.WHAT_GOES_HERE(mykeys)
[3, 1]

Answer

A list comprehension seems to be a good way to do this:

>>> [mydict[x] for x in mykeys]
[3, 1]
