Question

a) (1,2,3,[8,9])
b) (1,2,3,’Good’)
c) (11,)
d) (111)

Answer 1

ANSWER.

• All except fourth option is a valid tuple.

EXPLANATION:

• A tuple is an type of list which is ordered and unchangeable. Tuples  are enclosed within round brackets. If there is only 1 element present for the tuple, then it will not be considered as tuple unless we write a comma after the element. So, here, first three options are valid and the fourth one is invalid.
• We can also check our result by using type() method. See the attachment.
• Note: Tuples can be nested, we can also store list inside a tuple.
