How does defaultdict work?

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 diction that doesn’t exist, defaultdict will create a new key for you instead of throwing a KeyError.
defaultdict forces a dictionary to only accept keys that are the data type specified when you created the defaultdict.
defaultdict stores a copy of a dictionary in memory that you can default to if the original gets unintentionally modified.

Which statement about static methods is true?

Static methods serve mostly as utility or helper methods, since they cannot access or modify a class’s state.
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 are called static because they always return None.

What does calling namedtuple on a collection type return?

a tuple subclass with iterable named fields.
a tuple subclass with non-iterable parameter fields.
a generic object class with iterable parameter fields.
a generic object class with non-iterable named fields

According to PEP 8 coding style guidelines, how should constant values be named in Python?

in lowercase with underscores to seperate words – eg., max_value = 255
in all caps with underscores seperating words – eg., MAX_VALUE = 255
in mixed case without using underscores to seperate words – e.g., MaxValue = 255
in camel case without underscores to seperate words – eg., maxValue = 255

Describe the functionality of a deque.

A deque adds items at either or both ends, and remove items at either or both ends.
A deque adds items only to the top, but remove items from either or both sides.
A deque adds items to one side and remove items from the other side.
A deque adds items to either or both sides, but only removes items from the top.

What is the correct syntax for calling an instance method on a class named Game?

my_game = Game()self.my_game.roll_dice()
my_game = Game(self)
self.my_game.roll_dice()
my_game = Game(self) my_game.roll_dice(self)
my_game = Game()my_game.roll_dice()

Which statement about class methods is true?

A class method holds all of the data for a particular class.
A class method is similar to a regular function, but a class method does not take any arguments.
A class method is regular function that belongs to a class, but it must return None.
A class method can modify the state of the class, but it cannot directly modify the state of an instance that inherits from that class.
