Iterate over a specific column in a dictionary in Python -


i'm trying iterate on second column (first index) in dictionary similar to:

dict    =   { "me": [("blue", 37, 1,  2, "up", "left")], "you": [("green",  03, 3, 4, "up", "right"),     ("red", 29, 5, 6, "down", "right"),     ("yellow", 35, 7,  8, "straight", "down")], "them": [("black", 08, 9, 10, "up", "up"),     }

and retrun largest value. have is:

    c in dict[1:2]:      x = 0      if c > x:          x = c  return x

i'm getting unhashable type error. know has how code iterates on dictionary i'm stuck on how fix it. language python. wrong here? appreciated!

have tried using dict.iteritems() iterate on key-value pairs?

ex:

for key, val in dic.iteritems():     print "key: " + str(key) + "\t value:" + str(val)
