Problem: Given a Python tuple with n elements. How to convert it into a list with the same n elements?
Examples:
- Convert tuple
(1, 2, 3, 4, 5)into list[1, 2, 3, 4, 5]. - Convert tuple
('Alice', 'Bob', 'Ann')into list['Alice', 'Bob', 'Ann']. - Convert tuple
(1,)into list[1].
Note Tuple: Tuples are similar to lists—with the difference that you cannot change the tuple values (tuples are immutable) and you use parentheses rather than square brackets.
Solution: Use the built-in Python list() function to convert a list into a tuple. You don’t need to import any external library.
Code: The following code converts the three given tuples into lists.
tuple_1 = (1, 2, 3, 4, 5)
print(list(tuple_1))
# [1, 2, 3, 4, 5] tuple_2 = ('Alice', 'Bob', 'Ann')
print(list(tuple_2))
# ['Alice', 'Bob', 'Ann'] tuple_3 = (1,)
print(list(tuple_3))
# [1]
Try It Yourself: With our interactive code shell, you can try it yourself. As a small exercise, try to convert the empty tuple () into a list and see what happens.
Explanation: You can see that converting a tuple with one element leads to a list with one element. The list() function is the easiest way to convert a tuple into a list. Note that the values in the tuple are not copied—only a new reference to the same element is created:
The graphic also shows how to convert a tuple back to a list by using the tuple() function (that’s also a Python built-in function). Thus, calling list(tuple(lst)) on a list lst will result in a new list with the same elements.
