How do I deep copy tuples in Python for production systems?

In Python, tuples are immutable, meaning they cannot be changed after their creation. However, if you want to create a deep copy of a tuple, especially when it contains mutable objects, you must take special care to ensure all nested mutable objects are copied. This is particularly important in production systems to avoid unintended side effects.

import copy

# Original tuple containing a list
original_tuple = (1, 2, [3, 4])

# Creating a deep copy of the tuple
deep_copied_tuple = copy.deepcopy(original_tuple)

# Modifying the copied list within the tuple
deep_copied_tuple[2][0] = 'Modified'

print("Original tuple:", original_tuple)  # Output: (1, 2, [3, 4])
print("Deep copied tuple:", deep_copied_tuple)  # Output: (1, 2, ['Modified', 4])
