大神，求助啊，不知道怎么回事就是有问题

filename = 'sdf.txt'
while True:
        print('\nWhy do you choose IT program?')
        survey_reason = input('Let us see your reason:\n')
        quit_input = input('If no more,Enter quit when you are finished:\n')
        if quit_input == 'quit':
                break
        print('------')
        with open(filename) as file_object:
        if file_object.readline() != None:
                        with open(file_object,'a') as file_a:
                                file_a.write(survey_reason + '\n')
                else:
                        with open(file_object,'w') as file_w:
                                file_w.write(survey_reason + '\n')

缩进别用tab

if 判断下的缩进有问题这都看不出来？

用四个空格代替tab应该就好了。
