Python-使用 lambda 访问字典的值

Question

Given dict:

dict=[{'Confirmed_cases': {'Brazil': 1600,'Indonesia': 2400}, 'Death_cases': {'Brazil':30, 'Indonesia': 68}]

how can i get 1600 values from confirmed_cases using lambda? based on user input = Brazil.

Answer 1

This should work:

data = [{'Confirmed_cases' : {'Brazil' : 1600,'Indonesia' : 2400}, 'Death_cases': {'Brazil' :30, 'Indonesia' : 68}}]
confirmed_cases = lambda x: data[0]['Confirmed_cases'][x]
print(confirmed_cases('Brazil')) # > 1600

Not sure if its a good practice to name your dictionaries dict though. I would imaging its a reserved name.

Hope I could help: :)

Answer 2

This can help you out. This will ask for user input and run on while loop. If you don't want you can remove the while loop

yourDict = [{'Confirmed_cases': {'Brazil': 1600, 'Indonesia': 2400},
             'Death_cases': {'Brazil': 30, 'Indonesia': 68}}]


while True:
    country = str(input())
    if country in yourDict[0]['Confirmed_cases']:
        print(yourDict[0]['Confirmed_cases'][country])
    else:
        print("Please select from the list below ", str(list(yourDict[0]['Confirmed_cases'])))

Input:

Brazil

output:

1600
