Question

Which of the following statements is false?

a-Lists and tuples are built-in sequence collections.
b-Dictionaries, strings and sets are built-in non-sequence collections.
c-A dictionary is an unordered collection which stores key–value pairs that map immutable keys to values, just as a conventional dictionary maps words to definitions.
d-A set is an unordered collection of unique immutable elements.

Answer 1

The false statement is that strings are non-sequence collections when, in fact, they are considered sequence collections because they maintain the order of characters.

Step-by-step explanation:

The statement that is false is: "Dictionaries, strings and sets are built-in non-sequence collections." This statement is incorrect because strings are actually sequence collections in Python, not non-sequence collections. Let's clarify each point:

• Lists and tuples are indeed built-in sequence collections in Python. They maintain the order of elements in which they were added.
• Dictionaries and sets are built-in non-sequence collections. A dictionary is an unordered collection that holds key-value pairs where keys must be immutable. Meanwhile, a set is an unordered collection of unique, immutable elements.
• Strings are a sequence of characters and are considered as sequence collections because they maintain the order of characters.
