Python
Assessment

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?
count, fruit, price = (2, ‘apple’, 3.5)

tuple assignment // CORRECT

Q7.What built – in list method would you use to remove items from a list?

“””
sum(4, 3)

“””
return a + b

def sum(a, b): //CORRECT

Q12.What buit – in Python data type is commonly used to represent a stack?
set list // CORRECT

Q13.What would this expression return?
college_years = [‘Freshman’, ‘Sophomore’, ‘Junior’, ‘Senior’]
return list(enumerate(college_years, 2019)
[(‘Freshman’, 2019), (‘Sophomore’, 2020), (‘Junior’, 2021), (‘Senior’, 2022)]
[(2019, 2020, 2021, 2022), (‘Freshman’, ‘Sophomore’, ‘Junior’, ‘Senior’)]
[(‘Freshman’, ‘Sophomore’, ‘Junior’, ‘Senior’), (2019, 2020, 2021, 2022)]
[(2019, ‘Freshman’), (2020, ‘Sophomore’), (2021, ‘Junior’), (2022, ‘Senior’)] // CORRECT

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;
print(“There is a lot of people in the pool.”)
if num_people > 4;
print(“There are some people in the pool.”)
if num_people > 0;
print(“There are a few people in the pool.”)
else:
print(“There is no one in the pool.”)

————-
num_people = 5 // CORRECT

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?
An if / else statement executes one chunk of code if a condition it true, but a different chunk of code if the condition is false // CORRECT

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)
my_game = (Game) // CORRECT

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?
It is a null operation used mainly as a placeholder in functions, classes, etc. // CORRECT

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?
fruits = [‘apples’, ‘oranges’, ‘bananas’]
quantities = [5, 3, 4]
prices = [1.50, 2.25, 0.89]

# Desired output
[(‘Apples’, 5, 1.50),
(‘Oranges’, 3, 2.25),
(‘Bananas’, 4, 0.89)]

for fruit in fruits:
temp_qty = quantities[i]
temp_price = prices[i]
output.append((fruit, temp_qty, temp_price))
i += 1
return output
groceries = zip(fruits, quantities, prices) // CORRECT

Q32.What happens when you use the built-in function all() on a list?
The all() function returns True if all items in the list evaluate to True. Otherwise, it returns False. // CORRECT

Q33.What is the correct syntax for calling an instance method on a class named Game?

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..
