Question 1

What method can be used to place an item in the list at a specific index?
A) append
B) index
C) insert
D) Add

Accepted Answer

The insert() method allows you to specify the index at which you want to insert the item into the list. Append() adds the item to the end of the list, index() gives the index of the first occurrence of the item in the list, and Add() is not a valid method in Python.

Question 2

Which list will be referenced by the variable number after the execution of the following code? number = range(0, 9, 2)
A) [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
B) [1, 3, 5, 7, 9]
C) [2, 4, 6, 8]
D) [0, 2, 4, 6, 8]

Accepted Answer

The function range(0, 9, 2) generates a sequence of numbers starting from 0, incrementing by 2, and stopping before 9. Therefore, the list assigned to the variable number is [0, 2, 4, 6, 8].

Question 3

What would be the value of the variable list2 after the execution of the following code? list1 = [1, 2, 3]
List2 = []
For element in list1
List2.append(element)
List1 = [4, 5, 6]
A) [1, 2, 3]
B) [4, 5, 6]
C) [1, 2, 3, 4, 5, 6]
D) invalid code

Accepted Answer

The code appends each element of list1 to list2 before list1 is reassigned to a new list. Therefore, list2 contains the original elements of list1: [1, 2, 3].

Question 4

What are the data items in the list called?
A) data
B) elements
C) items
D) values

Accepted Answer

While "data", "items", and "values" can all be used to refer to items in a list, "elements" is the most commonly used term in the context of programming and computer science.

Question 5

When working with multiple sets of data, one would typically use a(n) _____.
A) list
B) tuple
C) nested list
D) Sequence

Accepted Answer

A nested list would allow for multiple sets of data to be stored within one list, each set of data being its own sublist. This would make it easy to access and manipulate each individual set of data while still keeping everything organized within one larger list.

Question 6

What is the advantage of using tuples over lists?
A) Tuples are not limited in size.
B) Tuples can include any data type as an element.
C) Processing a tuple is faster than processing a list.
D) There is no advantage.

Accepted Answer

Processing a tuple is faster than processing a list because tuples are immutable, meaning they cannot be changed after creation. This allows for faster access and iteration compared to lists, which are mutable and therefore require more overhead. However, this advantage comes at the cost of flexibility as tuples cannot be modified once created.

Question 7

What would you use if an element is to be removed from a specific index?
A) del statement
B) remove method
C) index method
D) slice method

Accepted Answer

The del statement is used to remove an element from a specific index in a list. The remove method is used to remove an element by its value, not its index. The index method is used to find the index of a specific element in a list. The slice method is used to extract a portion of a list, not to remove a specific element. Therefore, the best choice is A, del statement.

Question 8

What method can be used to convert a tuple to a list?
A) append
B) tuple
C) insert
D) list

Accepted Answer

The answer of What method can be used to convert...

Question 9

The remove method removes all occurrences of the item from a list.

Accepted Answer

The answer of The remove method removes all occurrences of...

Question 10

What would be the value of the variable list2 after the execution of the following code? list1 = [1, 2, 3]
List2 = list1
List1 = [4, 5, 6]
A) [1, 2, 3]
B) [4, 5, 6]
C) [1, 2, 3, 4, 5, 6]
D) invalid code

Accepted Answer

list2 is assigned to list1 before list1 is reassigned to [4, 5, 6]. Therefore, list2 will still hold the original values of [1, 2, 3] and not be affected by the reassignment of list1.

Question 11

The primary difference between a tuple and list is that _____.
A) when creating a tuple you don't use commas to separate elements
B) a tuple can only include string elements
C) a tuple cannot include lists as elements
D) once a tuple is created, it cannot be changed

Accepted Answer

Unlike lists, tuples are immutable, meaning they cannot be changed once created. The other options are incorrect. Tuples are created using commas to separate elements, can include any type of element (not just strings), and can include other tuples or lists as elements.

Question 12

What would be the value of the variable list after the execution of the following code? list = [1, 2, 3, 4]
List[3] = 10
A) [1, 2, 3, 10]
B) [1, 2, 10, 4]
C) [1, 10, 10, 10]
D) invalid code

Accepted Answer

The code assigns the value 10 to the fourth element of the list, which has an index of 3. Therefore, the resulting list will be [1, 2, 3, 10].

Question 13

What method can be used to convert a list to a tuple?
A) append
B) tuple
C) insert
D) list

Accepted Answer

The tuple method can be used to convert a list to a tuple, simply by wrapping the list in the tuple() constructor. The other options, such as append and insert, are list-specific methods that wouldn't be used for converting a list to a tuple.

Question 14

Invalid indexes do not cause slicing expressions to raise an exception.

Accepted Answer

Invalid indexes do not raise an exception in slicing expressions. Instead, they are simply ignored and treated as out-of-bounds, resulting in an empty sequence in the case of an empty slice or a shorter sequence if the slice is partially out-of-bounds.

Question 15

What would be the value of the variable list after the execution of the following code? list = [1, 2]
List = list * 3
A) [1, 2] * 3
B) [3, 6]
C) [1, 2, 1, 2, 1, 2]
D) [[1, 2], [1, 2], [1, 2]]

Accepted Answer

The expression list * 3 will create a new list with 3 copies of the elements in the original list. So, the resulting list will be [1, 2, 1, 2, 1, 2].

Question 16

Lists are dynamic data structures such that items may be added to them or removed from them.

Accepted Answer

Lists are dynamic data structures and allow items to be added or removed from them.

Question 17

A list cannot be passed as an argument to a function.

Accepted Answer

A list can be passed as an argument to a function in Python.

Question 18

What method or operator can be used to concatenate lists?
A) *
B) +
C) %
D) concat

Accepted Answer

The + operator can be used to concatenate lists by simply adding one list to another. For example, [1, 2, 3] + [4, 5, 6] would result in [1, 2, 3, 4, 5, 6]. Option A (*) is used for repeating items in a list, Option C (%) is used for string formatting, and Option D (concat) is not a valid Python operator.

Question 19

What is the first negative index in a list?
A) 0
B) -1
C) -0
D) Size of the string or list minus one

Accepted Answer

Negative indices start from -1, so the first negative index in a list is -1. Option A is incorrect because 0 is considered a non-negative index. Option C is invalid as -0 is not a valid index in Python. Option D is also incorrect as the size of the list or string minus one would give the index of the last element, not the first negative index.

Question 20

Arrays, which most other programming languages allow, have much more capabilities than list structures.

Accepted Answer

This statement is false. In Python, list structures have many capabilities and are commonly used in place of arrays in other programming languages. Lists in Python are dynamic and can hold elements of different data types, unlike arrays in other languages. Additionally, lists have built-in functions for sorting, appending, and inserting elements, making them highly versatile.
