python: how to generate pairs of cards in a deck

Suppose that I have the following variables:

suits = ["h","c", "d", "s"]
cards = ["2","3", "4", "5", "6", "7", "8", "9", "t", "j", "q", "k", "a"]
deck = []

for suit in suits:
    for card in cards:
        deck.append(str(card+suit))

I'd like to write a function that, given a specific card, generates the possible combinations of pairs.

For instance, generatePairs('a') should return something like:

['ahac','ahad','ahas','acad','acas','adas']

but I'm not sure how to approach writing that function.

you require something like

In [5]: deck = []

In [6]: for i in itertools.combinations(suits, 2):
   ...:     for j in cards:
   ...:         deck.append(j+i[0]+j+i[1])
   ...:

In [7]: print deck
['2h2c', '3h3c', '4h4c', '5h5c', '6h6c', '7h7c', '8h8c', '9h9c', 'thtc', 'jhjc', 'qhqc', 'khkc', 'ahac',
', '3h3d', '4h4d', '5h5d', '6h6d', '7h7d', '8h8d', '9h9d', 'thtd', 'jhjd', 'qhqd', 'khkd', 'ahad', '2h2s'
3s', '4h4s', '5h5s', '6h6s', '7h7s', '8h8s', '9h9s', 'thts', 'jhjs', 'qhqs', 'khks', 'ahas', '2c2d', '3c3
4c4d', '5c5d', '6c6d', '7c7d', '8c8d', '9c9d', 'tctd', 'jcjd', 'qcqd', 'kckd', 'acad', '2c2s', '3c3s', '4
 '5c5s', '6c6s', '7c7s', '8c8s', '9c9s', 'tcts', 'jcjs', 'qcqs', 'kcks', 'acas', '2d2s', '3d3s', '4d4s',
', '6d6s', '7d7s', '8d8s', '9d9s', 'tdts', 'jdjs', 'qdqs', 'kdks', 'adas']

In [7]: import itertools

In [8]: c = 'a'

In [9]: ['%s%s%s%s' % (c, s1, c, s2) for (s1, s2) in itertools.combinations(suits, 2)]
Out[9]: ['ahac', 'ahad', 'ahas', 'acad', 'acas', 'adas']
