If you're a Moneyball movie fan, you know that statistics helps teams find value in players that nobody else sees.

If you're a Moneyball movie fan, you know that statistics helps teams find value in players that nobody else sees. In this problem, you'll be implementing two functions to calculate the team batting average for one team, and the mean slugging percentage for all teams.

We highly encourage you to use the functions that you've defined before to solve these problems, specifically the common_players and get_players functions from the previous two problems.

Two functions have already been defined for you to calculate batting average and slugging percentage given a player's statistics. Use these functions when you calculate the averages for each team.
