print(multi_tuple)

Tuples are commonly used in Python to represent a set of data that does not need to be changed after it is created. A common example of using tuples in Python is when returning multiple values from a function.

For example, if a function calculates the mean and standard deviation of a set of numbers, it could return both values as a tuple:

• def calculate_stats(numbers):

  avg = sum(numbers) / len(numbers)

  std_dev = math.sqrt(sum((x - avg) ** 2 for x in numbers) / len(numbers))

  return avg, std_dev

  nums = [1, 2, 3, 4, 5]

  avg, std_dev = calculate_stats(nums)

  print("Average:", avg)

  print("Standard deviation:", std_dev)

They are also common in functions such as the zip() function that returns a list of tuples, each containing one element from each of the input lists.

• list1 = [1, 2, 3]

  list2 = ['a', 'b', 'c']

  zipped = zip(list1, list2)

  print(list(zipped))

In general, tuples are a convenient way to store and pass multiple values that are related to each other.
