records = [{'spam': 1, 'foo': 'z'}, {'spam': 2, 'foo': 'a'}]
sorted(records, key=lambda record: record['spam']) # default: ascending
# ==> [{'spam': 1, 'foo': 'z'}, {'spam': 2, 'foo': 'a'}]
sorted(records, key=lambda record: record['spam'], reverse=False) # ascending
# ==> [{'spam': 1, 'foo': 'z'}, {'spam': 2, 'foo': 'a'}]
sorted(records, key=lambda record: record['spam'], reverse=True) # descending
# ==> [{'spam': 2, 'foo': 'a'}, {'spam': 1, 'foo': 'z'}]
# -----------------------
sorted(records, key=lambda dictionary: dictionary['foo']) # default: ascending
# ==> [{'spam': 2, 'foo': 'a'}, {'spam': 1, 'foo': 'z'}]
sorted(records,key=lambda alias: alias['foo'], reverse=True) # descending
# ==> [{'spam': 1, 'foo': 'z'}, {'spam': 2, 'foo': 'a'}]
