Q1.What is an abstract class? class exists only so that other “concrete” classes can inherit from the abstract class.// CORRECT Q2.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. // CORRECT Q4.What is a static method? 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. They serve mostly as utility methods or helper methods, since they can’t access or modify a class’s state. // CORRECT Q5.What are attributes? class Function arguments are called “attributes” in the context of class methods and instance methods.// CORRECT Q6.What is the term to describe this code? tuple assignment // CORRECT Q7.What built – in list method would you use to remove items from a list? “.pop()” method // CORRECT Q8.What is one of the most common use of Python’s sys library? Q9.What is the runtime of accessing a value in a dictionary by using its key? “O(1)”, also called constant time // CORRECT Q10.What is the correct syntax for defining a class called Game? class Game: pass // CORRECT Q11.What is the correct way to write a doctest? sum(-4, 5) def sum(a, b): //CORRECT Q12.What buit – in Python data type is commonly used to represent a stack? Q13.What would this expression return? Q14.How does “defaultdict” work? “defaultdict” forces a dictionary to only accept keys that are of the types specified when you created the “defaultdict” (such as string or integers).// CORRECT Q15.What is the correct syntax for defining a class called “Game”, if it inherits from a parent class called “LogicGame”? class Game(LogicGame): pass // CORRECT Q16.What is the purpose of the “self” keyword when defining or calling instance methods? self refers to the instance whose method was called // CORRECT Q17.Which of these is NOT a characteristic of namedtuples? No import is needed to use namedtuples because they are available in the standard library // CORRECT Q18.What is an instance method? Instance methods can modify the state of an instance or the state of its parent class //CORRECT Q19.Which choice is the most syntactically correct example of the conditional branching? num_people = 5 if num_people > 10; ————- Q20.Which statement does NOT describe the object-oriented programming concept of encapsulation? It only allows the data to be changed by methods // CORRECT Q21.What is the purpose of an if / else statement? Q22.What buit – in Python data type is commonly used to represent a queue? list // CORRECT Q23.What is the correct syntax for instantiating a new object of the type Game? class(Game) Q24.What does the built-in map() function do? It applies a function to each item in an iterable and returns the value of that function. // CORRECT Q25.If you don’t explicitly return a value from a function, what happens? If the return keyword is absent, the function will return None. // CORRECT Q26.What is the purpose of the pass statement in
Python? Q27.What is the term used to describe items that may be passed into a function? arguments // CORRECT Q28.Which collection type is used to associate values with unique keys? dictionary // CORRECT Q29.When does a for loop stop iterating? when it encounters an if / else statement that contains a break keyword // CORRECT 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.// CORRECT Q31.Given the following three lists, how would you create a new list that matches the desired output printed below? # Desired output for fruit in fruits: Q32.What happens when you use the built-in function all() on a list? Q33.What is the correct syntax for calling an instance method on a class named Game? >> > dice.roll() // CORRECT Q34.Correct representation of doctest for function in Python def sum(a, b): //CORRECT return a + b What is the correct syntax for defining An_init__ method that sets instance specific attributes upon creation of a new class instance?This is Expert Verified Answer
The right syntax for defining an __init__() method that sets instance-specific attributes upon creation of a new class instance is def __init__(self): pass.
What is the term used to describe items that may be passed into a function Linkedin?Attributes are strings that describe characteristics of a class. Function arguments are called "attributes" in the context of class methods and instance methods.
What is the correct syntax for instantiating a new object of the type game in Python?Instantiating a class in Python is simple. To instantiate a class, we simply call the class as if it were a function, passing the arguments that the __init__ method defines. The return value will be the newly created object.
What is the correct way to write a Doctest Python Linkedin?Follow the below steps to write a function with doctest.. Import the doctest module.. Write the function with docstring. Inside the docstring, write the following two lines for testing of the same function. >>> ... . Write the function code.. Now, call the doctest. testmod(name=function_name, verbose=True) function for testing.. |
