Challenge Solution
2:28One solution to the list creation challenge.
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
To print out the goalkeeper's name then,
2:08
we need to remember to subtract
one from the keeper variable.
2:10
Score one for
another practice session done.
2:14
Thanks for working through it with me.
2:17
Keep up the momentum in
your Python learning.
2:19
With more practices like this,
you'll reach your goal soon.
2:22
Until next time, happy coding.
