Here is a small script to sort the dictionary based on key/choice
a = {"key3": 5 , "key2": 8, "key1": 2}
b = {"key2": 7 , "key1": 4, "key3": 9}
c = {"key1": 6 , "key3": 1, "key2": 1}
undecorated = [a, b, c] # how do you sort this list?
sort_on = "key3"
decorated = [(dict_[sort_on], dict_) for dict_ in [b]]
decorated.sort()
print decorated
print "-----------------------"
result = [dict_ for (key, dict_) in decorated]
print result
