Write a Python program that returns True if a value is a tuple.
(7, 4, 9, 2, 0), [7, 4]
(7, 4, 9, 2, 0) True [7, 4] False
isinstance(x, tuple).for value in [(7, 4, 9, 2, 0), [7, 4]]: print(value, isinstance(value, tuple))(7, 4, 9, 2, 0) True [7, 4] False

Write a Python program to swap two tuple variables.
A = (7, 4, 9), B = (3,)
A = (3,) B = (7, 4, 9)
A, B = (7, 4, 9), (3,)A, B = B, Aprint("A =", A)print("B =", B)A = (3,) B = (7, 4, 9)

Write a Python program to calculate the average of a tuple’s elements.
(5, 3, 9, 6)
5.75
sum / len.t = (5, 3, 9, 6)print(sum(t) / len(t))5.75

Write a Python program to count the distinct tuples in a list.
[(8, 9), (4, 7), (3, 6), (8, 9)]
3
len(set(data)).print(len(set([(8, 9), (4, 7), (3, 6), (8, 9)])))3

Write a Python program to find the tuples that appear in both lists, treating (3, 9) and (9, 3) as the same.
A = [(1, 5), (4, 8), (3, 9)], B = [(9, 3), (5, 6), (5, 1), (0, 4)]
{(3, 9), (1, 5)}A = [(1, 5), (4, 8), (3, 9)]B = [(9, 3), (5, 6), (5, 1), (0, 4)]norm_b = {tuple(sorted(t)) for t in B}print({t for t in A if tuple(sorted(t)) in norm_b}){(3, 9), (1, 5)}Sorting each tuple makes (9, 3) and (3, 9) identical.

Write a Python program to order tuples by the order of their keys in another list.
[("very", 8), ("i", 6), ("am", 5), ("happy", 0)], order ["i", "am", "very", "happy"][('i', 6), ('am', 5), ('very', 8), ('happy', 0)]data = [("very", 8), ("i", 6), ("am", 5), ("happy", 0)]order = ["i", "am", "very", "happy"]position = {key: i for i, key in enumerate(order)}print(sorted(data, key=lambda t: position[t[0]]))[('i', 6), ('am', 5), ('very', 8), ('happy', 0)]A position lookup dict is faster than calling order.index for every item.

Write a Python program to concatenate two tuples, and to nest them inside one tuple.
("s", "q", "a"), ("t", "o", "o", "l")('s', 'q', 'a', 't', 'o', 'o', 'l')
(('s', 'q', 'a'), ('t', 'o', 'o', 'l'))+ joins; (a, b) nests.a = ("s", "q", "a")b = ("t", "o", "o", "l")print(a + b)print((a, b))('s', 'q', 'a', 't', 'o', 'o', 'l')
(('s', 'q', 'a'), ('t', 'o', 'o', 'l'))New to this topic? Read the lesson, then come back.
Write a Python program to sort tuples by their minimum value.
[(1, 5, 7), (3, 4, 2), (4, 9, 0)]
[(4, 9, 0), (1, 5, 7), (3, 4, 2)]
key=min.print(sorted([(1, 5, 7), (3, 4, 2), (4, 9, 0)], key=min))[(4, 9, 0), (1, 5, 7), (3, 4, 2)]
