LinkedIn Python Assessment Questions with Answers 2022

What is an abstract class?

  • An abstract class is the name for any class from which you can instantiate an object.
  • An abstract class exists only so that other “concrete” classes can inherit from the abstract class
  • Abstract classes must be redefined any time an object is instantiated from them.
  • Abstract classes must inherit from concrete classes.

What happens when you use the build-in function any() on a list?

  • The any() function returns True if any item in the list evaluates to True. Otherwise, it returns False.
  • The any() function will randomly return any item from the list.
  • The any() function returns a Boolean value that answers the question “Are there any items in this list?”
  • The any() function takes as arguments the list to check inside, and the item to check for. If “any” of the items in the list match the item to check for, the function returns True.

What are attributes?

  • Attributes are strings that describe characteristics of a class.
  • Attributes are a way to hold data or describe a state for a class or an instance of a class.
  • Attributes are long-form version of an if/else statement, used when testing for equality between objects.
  • Function arguments are called “attributes” in the context of class methods and instance methods.

What data structure does a binary tree degenerate to if it isn’t balanced properly?

  • queue
  • set
  • linked list
  • OrderedDict

What statement about static methods is true?

  • Static methods are called static because they always return None.
  • Static methods can be bound to either a class or an instance of a class.
  • Static methods can access and modify the state of a class or an instance of a class.
  • Static methods serve mostly as utility methods or helper methods, since they can’t access or modify a class’s state.

What is the term to describe this code?

  • tuple assignment

How does defaultdict work? (Duplicate 1)

  • defaultdict will automatically create a dictionary for you that has keys which are the integers 0-10.
  • If you try to access a key in a dictionary that doesn’t exist, defaultdict will create a new key for you instead of throwing a KeyError.
  • defaultdict stores a copy of a dictionary in memory that you can default to if the original gets unintentionally modified.
  • defaultdict forces a dictionary to only accept keys that are of the types specified when you created the defaultdict (such as string or integers).

What built-in Python data type is commonly used to represent a stack?

  • [(2019, ‘Freshman’), (2020, ‘Sophomore’), (2021, ‘Junior’), (2022, ‘Senior’)]
  • [(‘Freshman’, ‘Sophomore’, ‘Junior’, ‘Senior’), (2019, 2020, 2021, 2022)]

How does defaultdict work? (Duplicate 2)

  • defaultdict will automatically create a dictionary for you that has keys which are the integers 0-10.
  • defaultdict forces a dictionary to only accept keys that are of the types specified when you created the defaultdict (such as strings or integers).
  • If you try to read from a defaultdict with a nonexistent key, a new default key-value pair will be created for you instead of throwing a KeyError.
  • defaultdict stores a copy of a dictionary in memory that you can default to if the original gets unintentionally modified.

What is the correct syntax for defining a class called “Game”, if it inherits from a parent class called “LogicGame”?

  • class Game.LogicGame(): pass

What is an instance method?

  • An instance method is any class method that doesn’t take any arguments.
  • Instance methods can modify the state of an instance or the state of its parent class.
  • Instance methods hold data related to the instance.
  • An instance method is a regular function that belongs to a class, but it must return None.

What is the purpose of the “self” keyword when defining or calling instance methods?

  • self means that no other arguments are required to be passed into the method.
  • self refers to the instance whose method was called.
  • There is no real purpose for the self method; it’s just historic computer science jargon that Python keeps to stay consistent with other programming languages.
  • self refers to the class that was inherited from to create the object using self.

Which of these is NOT a characteristic of namedtuples?

  • You can assign a name to each of the namedtuple members and refer to them that way, similarly to how you would access keys in dictionary.
  • Each member of a namedtuple object can be indexed to directly, just like in a regular tuple.
  • namedtuples are just as memory efficient as regular tuples.
  • No import is needed to use namedtuples because they are available in the standard library.

Assuming the node is in a singly linked list, what is the runtime complexity of searching for a specific node within a singly linked list?

  • The runtime is O(n) because in the worst case, the node you are searching for is the last node, and every node in the linked list must be visited.
  • The runtime cannot be determined unless you know how many nodes are in the singly linked list.
  • The runtime is O(1) because you can index directly to a node in a singly linked list.
  • The runtime is O(nk), with n representing the number of nodes and k representing the amount of time it takes to access each node in memory.

What happens when you use the built-in function all() on a list?

  • The all() function returns a Boolean value that answers the question “Are all the items in this list the same?
  • The all() function will return all the values in the list.
  • The all() function returns True if all the items in the list can be converted to strings. Otherwise, it returns False.
  • The all() function returns True if all items in the list evaluate to True. Otherwise, it returns False.
