示例输出（参见向下循环下一项时尝试）：

project/ $python project.py Address_Book.csv after.csv

 - y 
Type their fullname
 - Harry James potter
{'name0': {'\ufeffnickname': 'Harry', 'name': 'Harry James Potter', 'phone': 'N/A', 'address': '4 Pivet Drive Little Whinging, Surrey'}, 'name1': {'\uf
effnickname': 'Sirius', 'name': 'Sirius Black', 'phone': 'N/A', 'address': '12 Grimald Place London'}}
Person fullname already added
Person fullname already added
print row in data: {'\ufeffnickname': 'Harry', 'name': 'Harry James Potter', 'phone': 'N/A', 'address': '4 Pivet Drive Little Whinging, Surrey'}
print row in data: {'\ufeffnickname': 'Sirius', 'name': 'Sirius Black', 'phone': 'N/A', 'address': '12 Grimald Place London'}

这个问题是关于for循环的。在第一个for循环中，你可以看到我将用户输入的变量'name'与字典中的\ufeff昵称或名称进行比较，并打印出它是否已经存在于字典中。问题是我看不到下一步的方法，也就是对字典['name1']等等做同样的操作。当i = 0时，我做了一个while循环，然后在其中将其转换为字符串，并尝试连接字典变量，如if（response['name' + [i]]）.lower（）== name.lower（）：打印“person fullname already added”，但没有成功，因为它说我不能从列表中连接。我是一个初学者，我可能代码看起来很复杂，但任何建议或方法，从name0，name1等更改为使用\ufeff昵称数据，而不是每个字典标题将是有帮助的。
更新：这是我想到的到目前为止，它有点工作，但它卡住了，并结束了循环打印语句一遍又一遍：有什么解决办法吗？我觉得我什么都试过了。

count = (len(dictA) - 1)
    while (count >= 0):
        name_variable = 'name' + str(count)
        response = dictA
        for person in dictA:
            if (response[name_variable]['name']).lower() == name.lower():
                print("Person fullname already added")
            elif (response[name_variable]['\ufeffnickname']).lower() == 
    name.lower():
                print("Person nickname already added")
        count -= count
