Python Tuple Practice Problems
Write a Python program to join a tuple of characters into a string.
("s", "q", "a", "t", "o", "o", "l", "s")Sqatools
"".join(t).t = ("s", "q", "a", "t", "o", "o", "l", "s")print("".join(t).capitalize())Sqatools

Write a Python program to add an item to a tuple.
(18, 65, 3, 45), item 15
(18, 65, 3, 45, 15)
+.t = (18, 65, 3, 45)t = t + (15,)print(t)(18, 65, 3, 45, 15)
(15,) is a one-item tuple; the comma is required.

Write a Python program to assign the values of a tuple to several variables and print them.
(6, 7, 3)
a, 6 b, 7 c, 3
a, b, c = (6, 7, 3)print("a,", a)print("b,", b)print("c,", c)a, 6 b, 7 c, 3
The number of names must match the number of items.

Write a Python program to create a tuple containing values of different data types.
(2.6, 1, 'Python', True, [5, 6, 7], (5, 1, 4), {'a': 123, 'b': 456})
['float', 'int', 'str', 'bool', 'list', 'tuple', 'dict']mixed = (2.6, 1, "Python", True, [5, 6, 7], (5, 1, 4), {"a": 123, "b": 456})print(mixed)print([type(x).__name__ for x in mixed])(2.6, 1, 'Python', True, [5, 6, 7], (5, 1, 4), {'a': 123, 'b': 456})
['float', 'int', 'str', 'bool', 'list', 'tuple', 'dict']Listing the type names shows every item keeps its own type.

Write a Python program to create a list of tuples, each holding a number and its square.
[4, 6, 3, 8]
[(4, 16), (6, 36), (3, 9), (8, 64)]
(n, n * n) for each number.numbers = [4, 6, 3, 8]print([(n, n * n) for n in numbers])[(4, 16), (6, 36), (3, 9), (8, 64)]
The square of 3 is 9; the original sample showed 27, which is 3 cubed.

Write a Python program to find the maximum value in a tuple.
(41, 15, 69, 55)
69
max() works on any iterable.print(max((41, 15, 69, 55)))69

Write a Python program to create a tuple of pairs from two lists.
[4, 6, 8], [7, 1, 4]
((4, 7), (6, 1), (8, 4))
zip pairs items at the same position; tuple() collects the pairs.list1 = [4, 6, 8]list2 = [7, 1, 4]print(tuple(zip(list1, list2)))((4, 7), (6, 1), (8, 4))
zip yields (4, 7), (6, 1), (8, 4); tuple() stores them in a tuple.
