I have a python list which looks something like this:
A = [[1,1,2,2,3,3,3,3,3,3,4,4,4,4,4,3,3,3,3,7,7,7,7,7,3,3,3,3,3,8], [3,3,3,3,6,6,6,6,7,7,7,3,3,3,0,0,0],[5,5,5,3,3,3,2,2,2,8,8,8,3,3,3,3]]
A State change ‘On’ is defined as when we iterate over the sub-list within the List and there is a transition from any number to the number ‘3’. The state is assumed to be ‘On’ till the occurrence of number ‘3’ continues during iteration. Once there is transition from ‘3’ to any other number, the state is assumed to be ‘Off’. So in this Sub_list_0 within List A, there are 3 times that the state changes to ‘On’ since there are 3 times that the transitions to number ‘3’ happens from other numbers.
So basically I need to know the count of no of state transitions to ‘On’ state in each of the sub-list within the list A. The result for the above list should be like this:
Result_Sub_List_0: 3 Result_Sub_List_1: 2 Result_Sub_List_2: 2
Is there a way in python where this kind of functionality can be built in a simple and efficient manner?
Any help is highly appreciated.
