用Python完成猜随机数的游戏

from random import randint

name = raw_input()

f = open('game.txt')
lines = f.readlines()
scores = {}#初始化一个空字典
for l in lines:
s = l.split()

#print s[:]-----------------['yaoxiaokui', '1', '6', '6']

score = scores.get(name)
if score is None:
score = [0, 0, 0]

game_times = int(score[0])
min_times = int(score[1])

if game_times > 0:
avg_times = float(total_times) / game_times
else:
avg_times = 0
print '%s,你已经玩了%d次，最少%d轮猜出答案，平均%.2f轮猜出答案' %(name, game_times, min_times,avg_times)
print '输入数值的最大值'
max = input()
num = randint(1, max)
times = 0#记录本次游戏轮数
print 'Guess what i think?'
answer = input()
while answer!=num:
times += 1
if answer > num:
print 'too large'

print 'You Win!'

if game_times == 0 or times < min_times:
min_times = times
total_times += times

scores[name] = [str(game_times), str(min_times), str(total_times)]
result = ''
for n in scores:

f.write(result)
f.close()
