Creаte а clаss called PrezList that's a subclass оf the Pythоn built-in list class. PrezList оnly contains lists (sublists) with three attributes: the year a president took office, the name of the president, and the president's state of residence. Example: [1789, 'Washington', 'Virginia']. The year attribute is an integer, the other two are strings. When creating PrezList assume sublists can only be added via the append and insert methods. The input parameter for both methods will be a three item list, for example: [1861, 'Lincoln', 'Illinois']. The insert method also has an index parameter indicating where in the list to place the parameter sublist. Provide code for the class definition and the insert method. Do not provide code for the append method since it will be added later by someone else. Ensure the input parameter is a type 'list' with exactly three elements. Also validate that the year is an integer between 1789 and 2026, inclusive, and that the state is in this tuple: states = ('Alabama', 'Alaska', ''Arkansas', .... 'Wyoming') # 'states' has 51 entries for all U.S. states and D.C. Assume 'states' is available in your class as a class attribute and is accessible using 'PrezList.states'. Do not retype this tuple into your code - assume it's there. If the input to be added fails any of those checks return False and a short string stating the reason for the failure. Otherwise, use the parent's insert method to place the parameter sublist into PrezList, then return True and 'added'.
