Introduction
List basics
Lists with if statements and loops
Lists in functions
Instruction
Good. We often check the number of list elements using the len(list_name) function in if statements:
# check if there are any elements
if len(companies) > 0:
print('Some elements found')
else:
print('No elements found')
Exercise
You are again given the tourist arrivals in France (they are available in the tourist_arrival variable in the Code Editor), but a friend of yours experimented with it a little bit. He might have deleted some entries from the list.
Write a piece of code that will check whether there are exactly 12 items in tourist_arrivals. If there are exactly 12 items, do nothing. Otherwise, print:
Incorrect number of months.
Stuck? Here's a hint!
To check if the number of months is wrong, use:
if len(tourist_arrivals) != 12
