stability and complex sequencing Starting from python2.2, the ordering is guaranteed to be stable. This means that if multiple elements have the same key, their order of precedence will be the same before and after ordering.Copy the Code code as follows: >>> data = [(' Red ', 1), (' Blue ', 1), (' Red ', 2), (' Blue ', 2)] >>> sorted (data, Key=itemgetter (0)) [(' Blue ', 1), (' Blue ', 2), (' Red ', 1), (' Red ', 2)] Note that the order of the ' blue ' is maintained after sorting, that is, '

'), reverse = True)[('John', 'A', 15), ('Jane ',' B ', 12), ('Dave', 'B', 10)] 5) stable and complex sorting From python2.2, the sorting is ensured to be stable. It means that if multiple elements have the same key, their order remains unchanged before and after sorting. The code is as follows: >>> Data = [('red', 1), ('blue', 1), ('red', 2), ('blue', 2)]>>> Sorted (data, key = itemgetter (0 ))[('Blue', 1), ('blue', 2), ('red', 1), ('red', 2)] Note that the order of 'blue' after sorting is mai
