Also, you must raise exceptions when necessary.You must NOT use any other methods that **you implemented** in the assignment (everything must be done inline).Consider the following class definition:class SLLException(Exception): “”” Custom exception class to be used by Singly Linked List DO NOT CHANGE THIS CLASS IN ANY WAY “”” passclass SLNode: “”” Singly Linked List Node class DO NOT CHANGE THIS CLASS IN ANY WAY “”” def __init__(self, value: object) -> None: self._next = None self._value = valueclass LinkedList: def __init__(self, start_list=None): “”” Initializes a new linked list with front and back sentinels DO NOT CHANGE THIS METHOD IN ANY WAY “”” self._head = SLNode(None) self._tail = SLNode(None) self._head._next = self._tail # populate SLL with initial values (if provided) # before using this feature, implement add_back() method if start_list is not None: for value in start_list: self.add_back(value) def __str__(self) -> str: “”” Return content of singly linked list in human-readable form DO NOT CHANGE THIS METHOD IN ANY WAY “”” out = ‘SLL [‘ if self._head._next != self._tail: cur = self._head._next._next out = out + str(self._head._next._value) while cur != self._tail: out = out + ‘ -> ‘ + str(cur._value) cur = cur._next out = out + ‘]’ return out def length(self) -> int: “”” Return the length of the linked list DO NOT CHANGE THIS METHOD IN ANY WAY “”” length = 0 cur = self._head while cur._next != self._tail: cur = cur._next length += 1 return length def is_empty(self) -> bool: “”” Return True is list is empty, False otherwise DO NOT CHANGE THIS METHOD IN ANY WAY “”” return self._head._next == self._tail # —————————————————————— # def remove_at_index(self, index: int) -> None : “”” TODO: Write this implementation “”” returnComputer ScienceEngineering & TechnologyPython Programming CSE 310
