This is a part of the database, i cannot import all of it since it is too big 

Please fill in the ??? in Python. 

Your submission should include the following variables defined correctly:

career_rbis

max_rbis

max_player

career_rbis = { } # Open the file. Call it batting_file and the file name 'batting.csv'. ??? # Read the data from the file using a `for` loop. for line in batting_file.???: line = line.strip() # remove whitespace from the line values = ??? # split the line by commas ',' if values[ 0 ] == 'playerID': continue # skip the header line batter_id = ??? # get the batter_id rbis = ??? # get the RBIs # ignore non-digit RBIs ??? # check if batter_id is in career_rbis if batter_id not in career_rbis: # add it ??? else: # add the RBIs career_rbis[ batter_id ] = ??? # Find the player with the maximum RBIs. This will probably take # several lines of code and some serious thought on your part.
