which of the following is not a valid way to create a list?
my_list =
my_list = list()
my_list = (1, 2, 3)
my_list = 1, \hello\, 3.14

Explanation:

• Question 1: A list is an ordered collection of items that can be changed (mutable) after creation. Strings are ordered but immutable. Tuples are ordered and immutable. Int is a single - value data type, not a collection.
• Question 2: A set is an unordered collection of unique items. Strings are ordered. Lists are ordered. Tuples are ordered.
• Question 3: my_list=(1,2,3) creates a tuple, not a list. my_list = [] creates an empty list. my_list = list() also creates an empty list. my_list=[1,"hello",3.14] creates a list with mixed - type elements.

Answer:

• Question 1: List
• Question 2: Set
• Question 3: my_list=(1,2,3)
