Introduction
Tuple basics
Tuples in functions
Instruction
Good job! There are two special cases for defining tuples. If you want to create an empty tuple, you must use empty parentheses:
empty_tuple = ()
What if you want to create a tuple with a single item? You may use parentheses parentheses or not, but you must include a trailing comma:
single_item_tuple = (1,)
Without the comma, single_item_tuple will be an ordinary integer – even if you surround it with parentheses parentheses.
When you print such a tuple, the trailing comma will also be displayed.
print(single_item_tuple)
Result: (1,)
Exercise
Create a tuple named from_city with a single item: 'Paris'. Then print its value to the console.
Stuck? Here's a hint!
Remember about the trailing comma.
