Question 7 of 14intermediate🔧 ApplyShort Answer3 marks

Prove with the help of an example that the variable is rebuilt in case of immutable data types.

Correct Answer

A tuple is an immutable data type, which means that the elements of a tuple cannot be changed after it has been created. For example, if we create tuple1 = (1, 2, 3, 4, 5), we cannot modify its elements directly. Any attempt to change an element would lead to an error.

Since the elements cannot be changed, the variable needs to be rebuilt when we want to modify the data. We can create a new tuple with the desired values and assign it to the same variable name. For example, tuple1 = (10, 20, 30) creates a new tuple and reassigns it to tuple1. This process rebuilds the variable with new values, as the original tuple cannot be modified in place.

Explanation

The textbook context clearly states that 'Tuple is an immutable data type. It means that the elements of a tuple cannot be changed after it has been created. An attempt to do this would lead to an error.' This establishes that tuples cannot be modified. The concept of 'rebuilding' follows logically - since immutable objects cannot be changed, any modification requires creating a new object and reassigning it to the variable name. The example demonstrates this by showing how reassignment creates a new tuple rather than modifying the existing one.

Solution Steps

  1. Step 1: Identify that tuples are immutable data types from the context.

  2. Step 2: Explain that elements cannot be changed after creation.

  3. Step 3: Demonstrate with an example showing reassignment creates a new tuple (rebuilds the variable).
