League table in Python - it doesn't insert teams into the list
<p>I need to make a league table for a project. There has to be 3 files,2 files consist of 1 class and the last file is for running a program. I have done all of the parts but when I call a method to add a team, the program adds the name but it does not insert it into the list of teams(which should do). When I try to display the items in the list, the program displays an error message instead of showing the actual team.</p>

<p>How can I fix it?Any help would be appreciated. :)</p>
