如何提取所有价格并给出最小值?JSON请求

Question

我正试图获得所请求项目的最低价格。我不明白怎么回事。有人能帮忙吗?

import requests
import json

item = input('put your item here please :  ')
gg = item.replace(' ', '_')
response_url =  requests.get(f'https://api.warframe.market/v1/items/'+ gg +'/orders?include=item')
data = json.loads(response_url.text)
price = data['payload']['orders'][0]['platinum']
print(price)

下面是一个示例url: https://api.warframe.market/v1/items/mirage_prime_systems/orders?include=item

以下是data["payload"]["orders"]的一个小样本数据:

{'visible': True,
'order_type': 'buy',
'quantity': 1,
'platinum': 11,
'user': {'reputation': 4,
'region': 'en',
'avatar': 'user/avatar/60e52c93a4784b00c68db129.png?558d0a9d0e4627de50c4218bda527217',

你没有说明你所说的"最小价格"是什么意思;所以我假设你想要最低买入价和最低卖出价:

orders = data["payload"]["orders"]
min_buy_price = min(o["platinum"] for o in orders if o["order_type"] == "buy")
min_sell_price = min(o["platinum"] for o in orders if o["order_type"] == "sell")
