What is the difference between deepcopy() and copy() in Python?

[TatyOko28]

copy.copy() creates a shallow copy, meaning it only copies the references to nested objects instead of duplicating them. If the original object contains mutable objects (like lists or dictionaries), changes to the original will affect the copy.
copy.deepcopy() creates a deep copy, meaning it recursively copies all objects, ensuring that modifying the original does not affect the copy.
Example:

import copy

list1 = [[1, 2, 3], [4, 5, 6]]
shallow = copy.copy(list1)
deep = copy.deepcopy(list1)

list1[0][0] = 100  # Modify original list

print(shallow)  # [[100, 2, 3], [4, 5, 6]] (Affected)
print(deep)     # [[1, 2, 3], [4, 5, 6]] (Unaffected)
