f=file("E:\python\pycharm\python\game.txt")
score=f.read().split()
f.close()

没看出问题
你自己程序里加输出调试，看看 result 的值对不对，再看为什么没有写入

yamika

from random import randint
f=open('d:\Others\\text.txt')
score=f.read().split()
f.close()
cishu=int(score[0])
lunshu=int(score[1])
avg=int(score[2])
if cishu>0:
    avg=float(lunshu)/cishu
else:
    avg==0
print('游戏次数：%d,猜出所用的轮数：%d,平均每次所用轮数：%.2f'%(
    cishu,lunshu,avg))
num=randint(1,50)
print('猜一个1到50之间的数')
Biggo=False
time=0
while Biggo==False:
      time+=1
      answer=int(input())
      if answer>num:
          print('大了')
          Biggo==True
      if answer<num:
          print('小了')
          Biggo==True
      if answer==num:
          print('Biggo')
          Biggo==False
if cishu==0 or time<lunshu:
    lunshu==time
    cishu=cishu+1
    avg=float(lunshu)/cishu
data='%d,%d,%.2f'%(cishu,lunshu,avg)
f=open('d:\Others\\text.txt','w')
f.write(data)
f.clsoe()
能运行，但最后无法写入最新结果，自查半天也差不是原因，求教。。。

crossin先生

最后 close() 不是 clsoe
你这个应该直接就会有报错提示的，注意看报错信息

老师你好
运行代码提示
Traceback (most recent call last):
  File "C:/Users/chenh/PycharmProjects/untitled/1.py", line 9, in <module>
    game_times=int(score[0])
ValueError: invalid literal for int() with base 10: '\xef\xbb\xbf0'

这个报错一直出现，弄得摸不着头脑。
谢谢指教！

老师，用这句判断的用意何在？
if game_times == 0 or times < min_times:

我试过忽略上句直接用min_times=times一样可以达到效果

当然不一样……你这个每次都会刷新最小轮数，之前的成绩就被覆盖了
