I'm writing a python script that reads a players name and stats from a sentence in a .txt file, then updates their stats within a dictionary and then prints out their average stats. I'm having trouble with assigning multiple values to the same 'player' key, as well as getting the logic below it to correctly update the player stats. The .group part is giving me trouble too. How can I do this?

import re, sys, os, math
 

if len(sys.argv) < 2:
    sys.exit("Usage: %s filename" % sys.argv[0])
 
filename = sys.argv[1]
 
if not os.path.exists(filename):
    sys.exit("Error: File '%s' not found" % sys.argv[1])

line_regex = re.compile(r"^(\w+ \w+) batted (\d+) times with (\d+) hits and (\d+) runs")

f = open (filename)

playerStats = {'players': [atBats, hits, avgs]} 

for players in playerStats:
    player = line.group(1)
    atBat = line.group(2)
    hit = line.group(3)

if player in playerStats:
        playerStats[player][1] += atBat
        playerStats[player][2] += hit

if player not in players:
    player = line.group(1)
    playerStats[player][1] = line.group(2)
    playerStats[player][2] = line.group(3)
    avgs = 0

else: 
    playerStats[player][0] = player
    playerStats[player][1] = atBat
    playerStats[player][2] = hit
    playerStats[player][3] = 0

for player in players:
    avgs[player] = round(float(hits[player])/float(atBats[player]), 3) 

print "%s: %.3f" % (player, avgs[player])
