Complete the team class implementation. For the class method get_win_percentage(), the formula is: team_wins / (team_wins + team_losses) note: use floating-point division. Ex: if the input is: ravens 13 3 where ravens is the team's name, 13 is the number of team wins, and 3 is the number of team losses, the output is: congratulations, team ravens has a winning average! if the input is angels 80 82, the output is: team angels has a losing average.
