How do I deep copy tuples in Python safely and idiomatically?

In Python, tuples are immutable, which means that their contents cannot be modified after creation. Because of this immutability, you typically do not need to deep copy tuples in the same way you would with mutable data types like lists or dictionaries. However, if you have a tuple containing mutable objects, you may want to create a deep copy of the tuple to ensure that changes to the mutable objects do not affect the original tuple. This can be done using the `copy` module.

Here is a safe and idiomatic way to deep copy a tuple containing mutable objects:

import copy # Example of a tuple containing a list (mutable object) original_tuple = (1, 2, [3, 4]) # Deep copy the tuple deep_copied_tuple = tuple(copy.deepcopy(item) if isinstance(item, list) else item for item in original_tuple) # Modifying the list in the deep copied tuple deep_copied_tuple[2].append(5) print("Original Tuple:", original_tuple) # Outputs: (1, 2, [3, 4]) print("Deep Copied Tuple:", deep_copied_tuple) # Outputs: (1, 2, [3, 4, 5])
