from copy import deepcopy class Sorted_List: def has_duplicates (self): Determines whether source contains duplicate values. Use: duplicates = source.has_duplicates () Returns: duplicates - True if any value in this Sorted List appears more than once, otherwise False. IIIIII duplicates = False # Your code here return duplicates def apply(self, func): IIIIII Returns the values where func (value) is True. Use: values = source.apply(func) Parameters: func. - a function that given a node value returns True for some condition, otherwise returns False. Returns: values - a Python list of values where func(value) is True (list of *) IIIIII values = [] # Your code here return values
