Implement these functions from the template following the description (specification) in their docstring:

By default, this project does not generate any interesting printed output. So, you should use one of these strategies in your work:
- Use Python Tutor to do incremental development, focusing on one function at a time in isolation
- Invent some of your own intermediate output, to get feedback while in develop mode
- Submit your work to get feedback from unit tests
Hint: you can use random.randint(a, b) to select random numbers between a and b.

Here is the feedback for the parts of my code that are in correct:
11:play_lottery_once(), num matches is 3
Tests play_lottery_once() returns val when number of matches is 3
Test feedback
play_lottery_once() returned 5 when 3 numbers match in the lottery
12:play_lottery_once(), num matches is 4
Tests play_lottery_once() returns val when number of matches is 4
Test feedback
play_lottery_once() returned 20 when 4 numbers match in the lottery
13:play_lottery_once(), num matches is 5
Tests play_lottery_once() returns val when number of matches is 5
Test feedback
play_lottery_once() returned 100 when 5 numbers match in the lottery
I am pretty sure this is the part of the code that is causing these errors:
elif matches == 3:
return 5
elif matches == 4:
return 20 # Win $20
elif matches == 5:
return 100 # Win $100
