我正在嘗試使用來自 python 的兩個用戶輸入來解析來自 JSON URL 文件的信息

Question

這是通過詢問用戶輸入而成功運行的代碼，在本例中為 state

import requests
import simplejson as json

response = requests.get("https://api.covidtracking.com/v1/states/ca/daily.json")

json_test = response.json()

print("Enter the state for which the COVID data should be retrieved (e.g. TX): ")
user_state = input()


count = 0
for i in json_test:
    i = count
    count = count + 1
    state = (json_test[i]['state'])
    dates = (json_test[i]['date'])
    

    if state == user_state:
            
        death = (json_test[i]['death'])
        print("State: " + str(state))
        print("Date: " + str(dates))
        print("Death(s)" + str(death))
        print("===============")

output 將類似於：

Date: 20201112
Death(s)18108
===============
State: CA
Date: 20201111
Death(s)18070
===============
State: CA
Date: 20201110
Death(s)18001
===============
State: CA
Date: 20201109
Death(s)17977
===============

但我正在嘗試實現用戶在命令行上輸入 US state 和日期的選項，如下所示：

Enter the state for which the COVID data should be retrieved (e.g. TX): CA
Enter the date for which the COVID data should be retrieved (e.g. 20201219): 20210219

我試過的代碼是：

import requests
import simplejson as json

response = requests.get("https://api.covidtracking.com/v1/states/ca/daily.json")

json_test = response.json()

print("Enter the state for which the COVID data should be retrieved (e.g. TX): ")
user_state = input()
print("Enter the date for which the COVID data should be retrieved (e.g. 20201219): ")
user_date = input()

count = 0
for i in json_test:
    i = count
    count = count + 1
    state = (json_test[i]['state'])
    dates = (json_test[i]['date'])
    

    if state == user_state and dates == user_date:
            
        death = (json_test[i]['death'])
        print("State: " + str(state))
        print("Date: " + str(dates))
        print("Death(s)" + str(death))
        print("===============")

但是，我的 output 沒有結果，但也沒有錯誤。 我現在知道為什么它不起作用

這里從 url 收到的日期值具有int數據類型，您需要將其轉換為string以進行比較。 此代碼將完美運行：

import requests
import simplejson as json

response = requests.get("https://api.covidtracking.com/v1/states/ca/daily.json")

json_test = response.json()


user_state = input("Enter the state for which the COVID data should be retrieved (e.g. TX): ")

user_date = input("Enter the date for which the COVID data should be retrieved (e.g. 20201219): ")

count = 0
for i in json_test:
    i = count
    count = count + 1
    state = (json_test[i]['state'])
    dates = (json_test[i]['date'])


    if((state == user_state)and(str(dates) == user_date)):

        death = (json_test[i]['death'])
        print("State: " + str(state))
        print("Date: " + str(dates))
        print("Death(s): " + str(death))
        print("===============")

輸入

Enter the state for which the COVID data should be retrieved (e.g. TX): CA
Enter the date for which the COVID data should be retrieved (e.g. 20201219): 20210305

Output

State: CA
Date: 20210305
Death(s): 53448
