ONE input => THREE outputs

[DeaD_EyE]

For mutable objects, copy.copy and/or copy.deepcopy can be used.
Lists, Dicts, Sets have a copy method.
Lists can also copied with:

import copy


my_list_1 = [1, 2, 3]
my_list_2 = my_list_1[:]
my_list_3 = my_list_1.copy()
my_list_4 = copy.copy(my_list_1) 

Lists can keep also lists and other objects.
To copy them together with the nested content, copy.deepcopy should be used.

import copy


nested_list_1 = [1, 2, [3, 4, 5], 6]
nested_list_2 = nested_list_1[:] # the inner list is not copied
nested_list_3 = copy.deepcopy(nested_list_1) # inner list is also copied

nested_nested_list_1 = [[[1]], [[2]]]
nested_nested_list_2 = copy.deepcopy(nested_nested_list_1)

# now changing the 1 to 66
nested_nested_list_2[0][0][0] = 66

# nested_nested_list_1 has the original value 1
# nested_nested_list_2 has instead 66
print(nested_nested_list_1)
print(nested_nested_list_2)
