LIST and ARRAY in PYTHON

Question 1

are the data structures that are used to store multiple items. They both support the indexing of elements to access them, slicing, and iterating over the elements

Answer 1

lists and arrays

Question 2

Accessing element is fast in __ ___ because they are in a contiguous manner but insertion and deletion is quite expensive because all the elements are shifted from the position of inserting and deleting element linearly

Answer 2

Python Arrays

Question 3

Accessing an element in a __ ___ is the same as an Array because a List is actually a dynamic array

Answer 3

Python List

Question 4

in Python is an inbuilt collection of items that can contain elements of multiple data types, which may be either numeric, character logical values, etc. It is an ordered collection supporting negative indexing.

Answer 4

list

Question 5

A list can be created using

Answer 5

[] containing data values

Question 6

is a vector containing homogeneous elements i.e. belonging to the same data type. Elements are allocated with contiguous memory locations.

Answer 6

array

Question 7

by using the array() function of the array module and see its type using the

Answer 7

type() function.

Question 8

Can consist of elements belonging to different data types

Answer 8

List

Question 9

Only consists of elements belonging to the same data type

Answer 9

Array

Question 10

No need to explicitly import a module for the declaration

Answer 10

list

Question 11

Can directly handle arithmetic operations

Answer 11

array

Question 12

Cannot directly handle arithmetic operations

Answer 12

list

Question 13

Need to explicitly import the array module for declaration

Answer 13

array

Question 14

Greater flexibility allows easy modification (addition, deletion) of data

Answer 14

list

Question 15

Preferred for a shorter sequence of data items

Answer 15

list

Question 16

Preferred for a longer sequence of data items

Answer 16

array

Question 17

Less flexibility since addition, and deletion has to be done element-wise

Answer 17

array

Question 18

The entire list can be printed without any explicit looping

Answer 18

list

Question 19

Consume larger memory for easy addition of elements

Answer 19

list

Question 20

A loop has to be formed to print or access the components of the array

Answer 20

array

Question 21

Nested ___ can be of variable size

Answer 21

lists

Question 22

Comparatively more compact in memory size

Answer 22

array

Question 23

Nested __ has to be of same size.

Answer 23

arrays

Question 24

for counting a particular element in the list

Answer 24

count()

Question 25

sort the complete list

Answer 25

sort()

Question 26

gives maximum of the list

Answer 26

max()

Question 27

gives minimum of the list

Answer 27

min()

Question 28

gives sum of all the elements in list for integer list

Answer 28

sum()

Question 29

gives first index of the element specified

Answer 29

index()

Question 30

adds the element to the end of the list

Answer 30

append()

Question 31

removes the element specified

Answer 31

remove()

Question 32

are specifically used to store a collection of numeric elements that are all of the same type

Answer 32

Arrays

Question 33

are more flexible than arrays in that they can hold elements of different types (integers, strings, objects, etc.)

Answer 33

Lists

Question 34

my_list = [1, 2, 2, 3] my_set = {1, 2, 2, 3} # Output will be {1, 2, 3}

Answer 34

list can contain duplicate element while set does not support operations that depend on sequence

Question 35

An unordered collection of key-value pairs

Answer 35

Dictionary

Question 36

Used to remove the first occurrence of a specific value from a list. Does not return the removed element. Raises a ValueError if the specified value is not found.

Answer 36

remove()

Question 37

Removes an element at a specific index and returns it. If no index is specified, __ removes and returns the last item in the list. Raises an IndexError if the specified index is out of range.

Answer 37

pop or pop()

Question 38

is a linear list of elements. It is like a single row of data, where each element can be accessed using a single index.

Answer 38

one-dimensional array

Question 39

can be thought of as a table or a matrix with rows and columns. It requires two indices to access an element: one for the row and one for the column.

Answer 39

two-dimensional array

Question 40

extends beyond two dimensions, requiring more than two indices to access its elements. The concept generalizes from 1D and 2D arrays to higher dimensions, such as 3D, 4D, etc.

Answer 40

multidimensional array
