我希望能够使用日期找到特定的数据

Question

这是一些数据的字典。当我打印它时，它会以两个不同的列打印出来。我在这里查看了如何搜索它并找到特定的数据，但这对我来说没有任何意义。如果您能告诉我如何搜索（使用日期）然后打印出数据，我将不胜感激。

rainfall = {

    '01/08/2014':1.0,

    '21/01/2015':0.20,

    '22/01/2015':0.10,

    '23/01/2015':1.00,

    '24/01/2015':0.30,

    '25/01/2015':0.40,

    '26/01/2015':0.75,

    '27/01/2015':0.20,

    '28/01/2015':1.00,

    '29/01/2015':0.20,

    '30/01/2015':0.20,

    '31/01/2015':0.30,

    }

for k, v in rainfall.items():

    print(f'{k:<4} - {v}')

def searching_for_data():

    whatdata=input("What date would you like to find (format: DD/MM/YYYY)")

    if whatdata in rainfall:

        print(find(whatdata))

finddata=input("Would you like to find a specific piece of data?")

if finddata == "Yes":

    searching_for_data()

Answer 1

你需要改变：if&nbsp;whatdata&nbsp;in&nbsp;rainfall: &nbsp;&nbsp;&nbsp;&nbsp;print(find(whatdata)至if&nbsp;whatdata&nbsp;in&nbsp;rainfall.keys(): &nbsp;&nbsp;&nbsp;&nbsp;print(rainfall[whatdata])
