this is a python question, any clues on how to approach the proposed output for the defined function? write in python thanks!

the length of some number Example: k=4,[123,1234,12345]>[123,1234,1234]; (5) (' last', k): takes the last k digits of the number, note k might be larger than the length of some number Example: k=4,[123,1234,12345]>[123,1234,2345]; (6) ('reduce_last', k ): replaces the last k numbers with their sum, assume k is always less than the length of the list Example: k=3,[1,2,3,4,5,6]>[1,2,3,4+5+6]=[1,2,3,15]. Notes: 1. You may assume that the provided operations would never cause any error, and the list will never be empty at any point during the execution. 2. Create one function at the time and test it, before moving on to the next one. Example: lst =[1,12,123,1234,12345,123456] operations =[( 'add', 5) ),( 'last', 3), ('reduce_last', 2) ] def session_money(lst, operations): "I"" >> lst =[1,12,123,1234,12345,123456] > operations_1 =[( 'add', 5), ('last', 3), ('reduce_last', 2) ] \>> session_money (lst, operations_1) [6,17,128,239,811] > operations_2 =[( first', 3), ('combine', 2), ('lose', 10) ] >>>ession_money (lst, operations_2) [3,125,236,236,236]
