Question

1. which of the following statements create a dictionary? select all correct responses. d = (33:\autumn\, 27:\michelle\) d = {} d = {\autumn\:33, \michelle\:27} d = {33:\autumn\, 27:\michelle\} 2. which of the following is a python list? (5, 6, 7) {5, 6, 7} {} 5, 6, 7 3. which of the following is a python set? {2, 3, 4} (2, 3, 4) 2, 3, 4 {}

Explanation:

Step1: Recall dictionary syntax

In Python, a dictionary is created using curly - braces {} with key - value pairs separated by colons : and pairs separated by commas. An empty dictionary is {}. A key - value pair in a dictionary looks like key:value.
The first option d = (33:"autumn", 27:"michelle") uses parentheses which is incorrect for a dictionary.
The second option d = {} is an empty dictionary.
The third option d = {"autumn":33, "michelle":27} is a dictionary with string keys and integer values.
The fourth option d = {33:"autumn", 27:"michelle"} is a dictionary with integer keys and string values.

Step2: Recall list syntax

In Python, a list is created using square - brackets []. So [5, 6, 7] is a Python list. The option (5, 6, 7) is a tuple, {5, 6, 7} is a set (if the elements are hashable), and {} is an empty dictionary.

Step3: Recall set syntax

In Python, a set is created using curly - braces {} for non - empty sets (when elements are provided) or the set() function for an empty set. So {2, 3, 4} is a Python set. The option (2, 3, 4) is a tuple, [2, 3, 4] is a list, and {} is an empty dictionary.

Answer:

1. B. d = {}, C. d = {"autumn":33, "michelle":27}, D. d = {33:"autumn", 27:"michelle"}
2. D. [5, 6, 7]
3. A. {2, 3, 4}
