Dictionary

Set

List

Question 3

Correct Answers: 1/4

How do you create a thread in Python using the 'threading' module?

threading.start(function_name)

run_thread(function_name)

Question 4

Correct Answers: 1/4

What is the purpose of the 'is_alive()' method in threading?

To make a thread sleep

To stop a thread

To check if a thread has finished execution

To start a new thread

Question 5

Correct Answers: 1/4

Which algorithm is used for sorting a list in Python by default?

Bubble Sort

Tim Sort

Quick Sort

Merge Sort

Question 6

Correct Answers: 1/4

What is the difference between 'append()' and 'extend()' methods for lists in Python?

'append()' works only for numbers, 'extend()' works for all types

Both methods perform the same action

'append()' removes elements, 'extend()' adds elements

'append()' adds a single element, 'extend()' adds elements from another iterable

Question 7

Correct Answers: 1/4

Which sorting algorithm is the best choice for a nearly sorted list?

Insertion Sort

Merge Sort

Bubble Sort

Quick Sort

Question 8

Correct Answers: 1/4

How does Python's GIL (Global Interpreter Lock) affect multithreaded programs that use data structures like lists and dictionaries?

It makes dictionaries immutable when accessed from multiple threads

It speeds up the modification of shared data structures

It prevents multiple threads from executing Python bytecodes concurrently, even for thread-safe data structures

It allows true parallel execution of threads modifying lists

Question 9

Correct Answers: 1/4

Which Python module provides tools for asynchronous programming?

time

asyncio

multiprocessing

threading

Question 10

Correct Answers: 1/4

What is the time complexity for accessing an element by index in a list?

O(n^2)

O(log n)

O(1)

O(n)

Question 11

Correct Answers: 1/4

What is the main difference between 'deepcopy()' and 'copy()' in Python?

Both perform the same action

'copy()' is slower than 'deepcopy()'

'deepcopy()' creates a completely independent copy, including nested objects

'copy()' creates an exact copy, while 'deepcopy()' creates a reference

Question 12

Correct Answers: 1/4

Which of the following data structures maintains the insertion order of elements in Python?

Heap

Dictionary (before Python 3.7)

List

Set

Question 13

Correct Answers: 1/4

How do you set a thread as a daemon thread in Python?

thread.run_as_daemon()

thread.setDaemon(True)

set_daemon(thread, True)

thread.daemon = True

Question 14

Correct Answers: 1/4

What is the primary advantage of using a generator over a list?

Generators have more built-in methods

Generators can be indexed

Generators use less memory

Generators are faster to create
