Exploring Python Arrays and Tuples

How do you create an array in Python?

• You create an array in Python using square brackets, e.g., my_array = [1, 2, 3].

• You create an array in Python using parentheses, e.g., my_array = (1, 2, 3).

• You create an array in Python using curly braces, e.g., my_array = {1, 2, 3}.

• You create an array in Python by importing the array module, e.g., from array import array.

What is the main difference between a tuple and a list?

• Tuples can be resized while lists cannot.

• Lists can contain only numbers, while tuples can contain any data type.

• The main difference is that tuples are immutable and lists are mutable.

• Tuples are created using square brackets, while lists use parentheses.

How do you access the first element of a list?

• Use list[1] to access the first element of a list.

• Use list[0] to access the first element of a list.

• The first element can be retrieved using list.get(0).

• Access the first element with list.first() method.

What does it mean for a type to be mutable?

• A mutable type can be changed after creation.

• A mutable type is a type that cannot hold any data.

• A mutable type is always immutable.

• A mutable type cannot be changed after creation.

Can you change the value of an element in a tuple?

• No, you cannot change the value of an element in a tuple.

• Tuples can be modified using indexing.

• Yes, you can change the value of an element in a tuple.

• You can create a new tuple with the modified value.

What is the result of adding two lists together?

• The result is an error due to incompatible types.

• The result is a single list containing all elements from both lists.

• The result is a dictionary with the lists as keys.

• The result is a tuple containing the two lists.

How do you slice a list to get the first three elements?

• list[0:3]

• list[3:]

• list[:3]

• list[1:4]

What is a nested list? Give an example.

• [1, [2, 3], 4, 5]

• [[1, 2], [3, 4], [5, 6], [7, 8]]

• [1, 2, 3, 4, 5, 6]

• An example of a nested list is [[1, 2, 3], [4, 5, 6], [7, 8, 9]].

How do you find the length of a list in Python?

• my_list.length() gives the length of the list.

• Get the length by using my_list.size()

• Use count(my_list) to find the length.

• Use len(my_list) to get the length of a list.

What happens if you try to change an element in a tuple?

• The element is replaced without any error.

• The tuple remains unchanged without any error.

• A TypeError is raised.

• The tuple is automatically converted to a list.
