Review Python Tuples (Exercises)

00:00 Of course, we all know that just hearing about something doesn’t actually mean you know it. So here I’ve got a couple of review exercises for you to train the things you’ve learned about tuples before moving on to lists.

00:12 Feel free to do this at your own pace.

00:14 Create a tuple literal named location that holds the floating-point numbers 6.51 and 3.39, and then also the strings, "Lagos" and "Nigeria".

00:25 And they should be in that specific order.

00:28 Then use the index notation and the print() function to display the string at index two in location.

00:35 And finally, in a single line of code, you should unpack the values in location into four variables. Name them latitude, longitude, city, and country.

00:43 And then print each of these variables. We’ve got more for you. Use tuple() and a string literal to create a tuple called my_name that contains the letters of your name.

00:53 Then check whether the character "x" is in my_name using the in keyword. Finally, create a new tuple that contains all but the first letter of my_name and do that using slice notation.

01:07 So these are a few review exercises that can help you to fortify the information that you’ve learned about tuple. And when you’re done with them, you can move on to learning about lists.
