Assuming that my_tuple is a correctly created tuple, the fact that tuples are immutable means that the following instruction: my_tuple[1] = my_tuple[1] + my_tuple[0]

my_tuple[1] = my_tuple[1] + my_tuple[0]

• can be executed if and only if the tuple contains at least two elements
• is fully correct
• may be illegal if the tuple contains strings
• is illegal

Explanation: The operation is illegal because the ‘tuple’ object does not support item assignment.

Tuples are immutable sequences, which means you cannot update them directly – adding, changing, or removing tuple items requires different types of operations to be performed, for example converting the tuple to a list, updating the list, and converting it back to a tuple.
