Recap
Tuples as return types in functions
Tuples as records
List of tuples
Instruction
Very good! First of all, tuples are typically used to return multiple values from a single function. Take a look:
def count_spaces_commas_stops(text):
spaces, commas, stops = 0, 0, 0
for letter in text:
if letter == ' ':
spaces += 1
elif letter == ',':
commas += 1
elif letter == '.':
stops += 1
return (spaces, commas, stops)
The above function accepts a string argument named text and returns a tuple with three elements: the count of spaces in the text, the count of commas, and the count of full stops.
Exercise
Create a function named get_min_max_mean(numbers) that accepts a list of integer values and returns the smallest element, the largest element, and the average value respectively – all of them in the form of a tuple.
You can use the template code to test your function.
Stuck? Here's a hint!
Use the following for loop:
for number in numbers:
