Python Data types and purposes

Question 1

What is a complex???

Answer 1

Represents complex numbers, consisting of a real part and an imaginary part.
Example: x = 3 + 4j

Question 2

What is a list???

Answer 2

Ordered collection of items that can be of different types. Lists are mutable, meaning their elements can be changed after creation.
Example: my_list = [1, 2, ‘hello’, True]

Question 3

What is a Tuple???

Answer 3

Ordered collection of items similar to a list, but tuples are immutable, meaning their elements cannot be changed after creation.
Example: my_tuple = (1, 2, ‘hello’, True)

Question 4

What is a range???

Answer 4

Represents a sequence of numbers and is commonly used for looping a specific number of times.
Example: my_range = range(0, 10)

Question 5

What is a dictionary(dict)???

Answer 5

Collection of key-value pairs. Dictionaries are unordered, mutable, and can contain items of different data types.
Example: my_dict = {‘name’: ‘John’, ‘age’: 30, ‘city’: ‘New York’}

Question 6

What is a set???

Answer 6

Unordered collection of unique elements. Sets do not allow duplicate items.
Example: my_set = {1, 2, 3, 4}

Question 7

What is a frozenset???

Answer 7

Frozen Set (frozenset): Immutable version of a set. Once created, the elements of a frozenset cannot be changed.
Example: my_frozenset = frozenset({1, 2, 3})

Question 8

What is a bool???

Answer 8

Represents Boolean values, which can be either True or False.
Example: is_valid = True

Question 9

What is a bytes???

Example: my_bytes = b’hello’

Question 10

What is a memory view???

Answer 10

Provides a view of the memory occupied by an object. It allows for manipulation and interpretation of raw data.
Example: my_memory_view = memoryview(b’hello’)

Question 11
