Hi,list = [{'1': []}, {'2': []}, {'3': ['4', '5']}] I want to check for a value (e.g. '4'), and get the key of the dictionary that contains that value. (Yep, this is bizarre.) some_magic(list, '4') => '3' What's the functional way to do it? Is it possible to do it with a one-liner?
Yes: [key for d in list for key in d if '4' in d[key]] -- http://mail.python.org/mailman/listinfo/python-list
