LinkedIn Python Assessment Test Answers 2022
Q1. What's an abstract abstract class?
Associate abstract category could be a name for associated category from which you'll be able to instantiate an object.
Abstract categories should be redefined associated time an object is instantiated from them
Abstract categories should inherit from concrete categories.
Associate abstract category exists solely in order that alternative "concrete" categories will inherit from the abstract category.
Q2. What happens once you use the constitution to perform "any()" on a list?
The "any()" performs every way to return any item from the list.
The "any()" perform returns True if any item within the list evaluates to True. Otherwise, it returns False.

They serve largely as utility ways or helper ways since they can not access or modify a class's state.
Static ways will modify the state of a category or an instance of a category.
Q5. What are attributes?
Attributes are long-form versions of associate "if/else" statements, used once testing for equality between objects.
Attributes are the way to carry knowledge or describe a state for a category or associate instance of a category.
Attributes are strings that describe characteristics of a category.
Perform arguments are known as "attributes" within the context of sophistication ways and instance ways.
Q6. What's the term to explain this code?

Category Game: pass
def Game(): pass
def Game: pass
category Game(): pass
Q11. What's the right way to write a doctest?
Def sum(a, b):
"""
sum(4, 3)
7
sum(-4, 5)
1
"""
come back a + b
def sum(a, b):
"""
>>> sum(4, 3)
7
>>> sum(-4, 5)
1
"""
come back a + b

[(2019, 'Freshman'), (2020, 'Sophomore'), (2021, 'Junior'), (2022, 'Senior')]
Q14. However will "defaultdict" work?
"defaultdict" can mechanically produce a lexicon for you that has keys that are the integers 0-10
"defaultdict" forces a lexicon to solely settle for keys that are of the kinds such as once you created the "defaultdict" (such as string or integers).
If you are trying to access a key during a lexicon that does not exist, "defaultdict" can produce a brand-new key for you rather than throwing a "KeyError".
"defaultdict" stores a replica of a lexicon in memory that you just will default to if the initial gets accidentally changed.
Q15. What's the right syntax for outlining a category known as "Game", if it inherits from a parent category known as "LogicGame"?

every member of a named tuple object are often indexed to directly, a bit like during a regular tuple
named tuples ar even as memory economical as regular tuples
No import is required to use named tuples as a result of they're obtainable within the normal library
Q18. What's the associate instance method?
Instance ways will modify the state of associate instance or the state of its parent category
Instance ways hold knowledge associated with the instance
associate instance technique is any category technique that doesn't take any arguments
associate instance technique could be a regular perform that belongs to a category, however it should come back None

if num_people > 0;
print("There area unit many individuals within the pool.")
else:
print("There isn't anyone within the pool.")
Q20. That statement doesn't describe the object-oriented programming idea of encapsulation?
It protects the information from outside interference
A parent category is encapsulated and no information from the parent category passes on to the kid category
It keeps information and therefore the ways that may manipulate that information in one place
It solely permits the information to be modified by ways
Q21. What's the aim of AN if/else statement?
AN if/else statement tells the pc that chunk of code to run if the directions you coded area unit incorrect
AN if/else statement runs one chunk of code if all the imports were triple-crown, and another chunk of code if the imports weren't triple-crown
AN if/else statement executes one chunk of code if a condition it true, however a distinct chunk of code if the condition is fake
AN if/else statement tells the pc that chunk of code to run if there's enough memory to handle it. And that chunk of code to run if there's not enough memory to handle it

Q30. Assuming the node is in an exceedingly separately joined list, what's the runtime complexes of looking for a selected node among a separately joined list?
The runtime is O(n) as a result of within the worst case, the node you're looking for is that the last node, and each node within the joined list should be visited.
The runtime is O(NK), with n representing the amount of nodes and k representing the number of times it takes to access every node in memory.
The runtime can't be determined unless you recognize what percentage nodes are a unit within the separately joined list.
The runtime is O(1) as a result of you'll index on to a node in an exceedingly separately joined list.
Q31. Given the subsequent 3 lists, however would you produce a replacement list that matches the required output written below?
fruits = ['apples', 'oranges', 'bananas']
quantities = [5, 3, 4]
prices = [1.50, 2.25, 0.89]

[('Apples', 5, 1.50), ('Oranges', 3, 2.25), ('Bananas', 4, 0.89)]
output = []
fruit_tuple_0 = (first[0], quantities[0], price[0])
output.append(fruit_tuple)
fruit_tuple_1 = (first[1], quantities[1], price[1])
output.append(fruit_tuple)
fruit_tuple_2 = (first[2], quantities[2], price[2])
output.append(fruit_tuple)
return output
i = 0
output = []
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)
return groceries
i = 0
output = []
for fruit in fruits:
for qty in quantities:
for value in prices:
output.append((fruit, qty, price))
i += 1
return output

a = 1
b = 2
sum(a, b) = 3

come back a + b
- def sum(a, b):
"""
>>> a = 1
>>> b = 2
>>> sum(a, b)
