Welcome back. 0:00

How did you do? 0:01

If you weren't able to complete each task in the to-do list, that's okay. 0:02

Learning new things can be difficult, but by practicing them, you'll get better. 0:07

Okay, are you ready to see my approach? 0:12

Here we go. Open up team.py. 0:15

So our first to-do is to create an empty list to maintain the player names. 0:20

Remember that we can create a list with opening and closing hard brackets, and 0:24

since lists are mutable, we can start with an empty one and add to it as needed. 0:28

The next to do task is to take some input from the user and enter a loop. 0:33

A while loop seems like a good thing to use here. 0:38

Here we're asking if they want to add players to the list. 0:41

While they answer yes, we ask for a player's name to add to the team. 0:44

Then we use the append method to add the name to our player's list, and 0:49

ask if they want to add more. 0:53

If yes, the while loop continues. 0:55

If no, we move on to the next to-do task. 0:58

The next task is to print the number of players on the team. 1:02

Remember we use the Len method to get the number of items in our list. 1:06

We added in a bit of formatting with line breaks to add a nice touch as well. 1:10

The next task is to print the player number and the player name. 1:16

Sounds like a counter starting at the number one is an order here and 1:19

we'll need to increment that for each player in our list. 1:22

Our next task is to select our goalkeeper from the above roster. 1:26

Here, we're asking for the player number for our goalkeeper. 1:30

Again, using the Len method to help provide some context for 1:33

the user as to what to enter. 1:37

This next line, line 30, did you remember this? 1:39

Recall that taking input returns a string. 1:43

And for our indexing, we'll need that to be an integer. 1:46

All right, our next and last to-do, to print the goalkeeper's name. 1:50

Our printed out player numbers isn't using zero-based indexing, right? 1:55

Therefore when we select our goalkeeper, 2:00

our keeper variable is actually one higher than the zero-based players' list. 2:02
