Which of the following statements is true about tuples in Python?

Tuples in Python are designed to be immutable collections. This means that once a tuple is created, its contents cannot be modified—no additions, deletions, or changes in the values of its elements. This characteristic of immutability ensures that tuples can be utilized as keys in dictionaries and are hashable, which is not the case for mutable types like lists.

Moreover, tuples can indeed contain duplicate values. This allows for the representation of ordered collections where some elements may repeat, thus providing flexibility in how data is structured and accessed.

Combining these two aspects, the statements about the immutability of tuples and their ability to contain duplicate values lead to the conclusion that both are true. Consequently, the inclusion of both immutability and the allowance for duplicates in the answer supports a comprehensive understanding of tuples in Python.
