Step 3 – sort the birthdays
It can be hard to see if you have a match when there's just a list of random numbers.
It's a lot easier if you sort the list in to order first.
Python has a simple way to do this,
- Add a line to your program that says birthdays.sort()
This should sort the list of birthdays so that it's in order
- Run your program to check it works (Run > Run module)
- Run your program a few times. Do you get a match about half the time or not?
Remember, you might not get a match at all. You're dealing with totally random numbers.
