Making tuples by accident

Tuples are very powerful and useful, and it's super easy to make one by accident. All you have to do is create a variable and follow the assignment with a comma. This becomes an error when you try to use the variable later expecting it to be a string or a number.

You can verify the data type of a variable with the type() function. In this exercise, you'll see for yourself how easy it is to make a tuple by accident.
