Python内置函数输入

Question

我将这段代码作为一个Python文件运行，它将从内置的.py函数input中打开一个命令提示符。(这里没有太多的智慧...)如果我输入diagnose，按enter只有vav2_12会打印booya列表上的所有其他人都会打印not working

有人知道为什么吗？

#list of addresses of controllers
# format : key = name, v = (address, device_identifier) tuple
vavs = {'vav1_1': ('1701:1'),
        'vav1_2': ('1701:2'),
        'vav1_3': ('1701:3'),
        'vav1_4': ('1701:4'),
        'vav1_5': ('1701:5'),
        'vav1_6': ('1701:6'),
        'vav1_7': ('1701:7'),
        'vav1_8': ('1701:8'),
        'vav1_9': ('1701:9'),
        'vav1_10': ('1701:10'),
        'vav1_11': ('1701:11'),
        'vav1_12': ('1701:12'),
        'vav2_1': ('1701:13'),
        'vav2_2': ('1701:14'),
        'vav2_3': ('1701:15'),
        'vav2_4': ('1701:16'),
        'vav2_5': ('1701:17'),
        'vav2_6': ('1701:18'),
        'vav2_7': ('1701:19'),
        'vav2_8': ('1701:20'),
        'vav2_9': ('1701:21'),
        'vav2_10': ('1701:22'),
        'vav2_11': ('1701:23'),
        'vav2_12': ('1701:24'),
       }


#dict(TUPLE)[key]
d = dict(vavs)

while True:

    answer = input('Available actions: check_temps or diagnose?')

    if answer == 'check_temps':
        print('Checking Some Temps ...')


    if answer == 'diagnose':

        #print list of controller addresses
        for vav in vavs.items():
            print(vav[0])

        diagAnswer = input('Which VAV to check?')

        if vav[0] == diagAnswer:
            print('Booya')

        else:
            print('Not working')

    else:
        pass

Answer 1

因为VAV值是迭代之后来自vavs的最后一项。

我相信你的解决方案是这样的：

if diagAnswer in vavs.keys():
    print('Booya')
else:
    print('Not working')
