将变量从站点拉出来，使用相同的名称

-1

基本上我现在试图从sortedOptions部分只拉动所有SKU。我被告知这是json，不确定这是否正确。现在我只是拉第一个。我需要指定什么来吸引所有人？我最初尝试使用正则表达式，并没有拉任何信息，然后我被告知它是json，我需要使用json。到目前为止，这是我以前唯一能够从网站上获取任何东西的方法。将变量从站点拉出来，使用相同的名称

那么我的下一步就是将stock status和name只在同一部分。

CODE：从网站输出

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']

为什么你要转换的对象，把它们变回JSON字符串，然后再回到对象？ – jonrsharpe

它给了我一个错误，指出它需要是一个字符串，如果你有一个更直接的方法，请让我知道。这是我能够从此页面获取信息的唯一途径 –

您的代码无法使用。 –

您提供的JSON是无效的。无论如何，我假设“sortedOptions”是一个列表。所以，这应该让你明白：

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

如需更完整的答案，请提供有效的json。提供的一个tou是而不是。提示：使用curl或wget。

谢谢我使用这个你说什么，并得到它的工作 - '在数据选项['sortedOptions']： print（option ['product'] ['SKU']）' –

将变量从站点拉出来，使用相同的名称
