Question

我一直在我的程序中收到此错误，我不知道如何修复它。这是错误发生的地方。

def check_file(): 
       for read in range(6):
       length = len(linecache.getline('status.py', read))
       f = linecache.getline('status.py', read)[0:length-1]
       print (f)
       if read >= 6:
           print("5")
       else:
           file[read-1][1] = f
   return file

def change_state(change_till, state): # changes tills' status
    global file
    data = ''
    status = check_file()
    status[change_till-1][1] = state
    file = open('status.py', 'w')
    file.write(status[0][1]+'\n'+status[1][1]+'\n'+status[2][1]+'\n'+status[3][1]+'\n'+status[4][1])
    file.close()
    return state

我运行代码并出现此错误

TypeError: '_io.TextIOWrapper' object is not subscriptable.

有谁知道为什么会发生这种情况以及如何解决这个问题？
