python检查字典是否在列表中

Question

我有一个名为 clients_list 的列表，其中包含如下字典:

    clients_list =
    [
            {'John Guy': [28, '03171992', 'Student']},
            {'Bobby Jones': [22, '02181982', 'Student']},
            {'Claire Eubanks': [18, '06291998', 'Student']},
    ]

我如何使用输入的答案检查是否有人在此列表中？我试过代码

elif answer in clients_list:
    print(f'{answer} is in our database.')

但似乎不能正常工作。

Answer 1

试试这个

clients_list = [{'John Guy': [28, '03171992', 'Student']},
            {'Bobby Jones': [22, '02181982', 'Student']},
            {'Claire Eubanks': [18, '06291998', 'Student']}]

c= 'John Guy'

for item in clients_list:
    if c in item:
        print c + 'is in our database.'
        break
