Q1. What is an abstract class?

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

Q2. What happens when you use the build-in function “any()” on a list?

  • The “any()” function will randomly return any item from the list.
  • The “any()” function returns True if any item in the list evaluates to True. Otherwise, it returns False.
  • 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.

Q5. What are attributes?

  • Attributes are long-form version of an “if/else” statement, used when testing for equality between objects.

  • It applies a function to each item in an iterable and returns the value of that function.
  • It converts a complex value type into simpler value types.
  • It creates a mapping between two different elements of different iterables.

Q25. If you don’t explicitly return a value from a function, what happens?

  • The function will return a RuntimeError if you don’t return a value.
  • If the return keyword is absent, the function will return None.
  • If the return keyword is absent, the function will return True.
  • The function will enter an infinite loop because it won’t know when to stop executing its code.

Q30. 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 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.
  • 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.
