將變量從站點拉出來，使用相同的名稱

-1

基本上我現在試圖從sortedOptions部分只拉動所有SKU。我被告知這是json，不確定這是否正確。現在我只是拉第一個。我需要指定什麼來吸引所有人？我最初嘗試使用正則表達式，並沒有拉任何信息，然後我被告知它是json，我需要使用json。到目前爲止，這是我以前唯一能夠從網站上獲取任何東西的方法。將變量從站點拉出來，使用相同的名稱

那麼我的下一步就是將stock status和name只在同一部分。

CODE：從網站輸出

import requests 
import json 
r = requests.get('https://randomwebsite.com/') 
pull = r.json() 
print " " 

string = json.dumps(pull) 

parsed_json = json.loads(string) 
print parsed_json['name'] 
print parsed_json['SKU']

爲什麼你要轉換的對象，把它們變回JSON字符串，然後再回到對象？ – jonrsharpe

它給了我一個錯誤，指出它需要是一個字符串，如果你有一個更直接的方法，請讓我知道。這是我能夠從此頁面獲取信息的唯一途徑 –

您的代碼無法使用。 –

您提供的JSON是無效的。無論如何，我假設「sortedOptions」是一個列表。所以，這應該讓你明白：

for option in parsed_json['sortedOptions']: 
    print option.keys()

如需更完整的答案，請提供有效的json。提供的一個tou是而不是。提示：使用curl或wget。

謝謝我使用這個你說什麼，並得到它的工作 - '在數據選項['sortedOptions']： print（option ['product'] ['SKU']）' –

將變量從站點拉出來，使用相同的名稱
