elif循環中的python dict值

Question

每次我輸入一個值時，代碼都會給我“訂閱”...如何獲取 dict 值？

Friends = {
    'rolf' : 'blue',
    'ronnie' : 'green',
    'barbara' : 'purple',
    'benny' : 'kaki',
    'stewart' : 'yellow',
    'mickey' : 'red'
}


def greetagain():

    friend = input("Enter your friend name or color? ")
    i = Friends.values()

    if friend in Friends.keys():
        print('yes it matches')
    elif i in Friends.values():
        print('ok ok')
    else:
        print('subscribe')

greetagain()

歡迎來到 SO。 請注意下面的更改，您使用不帶i的變量朋友，因為您可以檢查朋友的值和鍵

def greetagain():

    friend = input("Enter your friend name or color? ")

    if friend in Friends.keys():
        print('yes it matches')
    elif friend in Friends.values():
        print('ok ok')
    else:
        print('subscribe')

我只能理解你的問題的一部分，所以，我已經盡力解釋了。

if 條件已經可以正常工作了。 我認為您想在 elif 條件中檢索朋友（鍵）的名稱，為此您可以嘗試以下代碼：

Friends = { 'rolf' : 'blue', 'ronnie' : 'green', 'barbara' : 'purple', 'benny' : 'kaki', 'stewart' : 'yellow', 'mickey' : 'red' }

def greetagain():
    friend = input("Enter your friend name or color? ")

    if friend in Friends.keys():
        print('Key matches')
        print("Color associted to friend is:", Friends[friend])
    elif friend in Friends.values():
        for key, value in Friends.items(): 
            if friend == value: 
                print('Color is present in list and associated by:', key)
    else:
        print('subscribe')

greetagain()
