python - 错误的 IF 语句输出

问题描述

我遍历了一个 API 返回的列表并抓取了 1.longName 2.RegularPrice 3.MarketCap 我已经完成但我希望市值返回“十亿美元”，如果它大于或等于 10 个数字，如果它也返回百万美元不到10位数。

import requests
import pprint
import json



url = "https://yahoo-finance15.p.rapidapi.com/api/yahoo/ga/topgainers"

querystring = {"start":"0"}

headers = {
    'x-rapidapi-host': "yahoo-finance15.p.rapidapi.com",
    'x-rapidapi-key': "9efd0f3e52mshd859f5daf34a429p11cb2ajsn2b0e421d681e"
    }

response = requests.request("GET", url, headers=headers, params=querystring)
data = response.json()

#print(response.text)


def new_stock(data):
    new_market = []

    for item in data ['quotes']:
        new_name = item.get ('longName')
        new_price = item.get ('regularMarketPrice')
        res_price = (f'{new_price} Dollars')
        cap =item.get('marketCap')
        cap2 = str(cap)
        for i in cap2:
            if i == 1000000000:
                return(f'{cap2} Billion Dollars')
            else:
                return(f'{cap2} million Dollars')
        return cap2



        new_market.append((new_name, res_price, cap2))

    return new_market

value = new_stock(data)
dict = {i: value[i] for i in range(0, len(value))}
print(dict)

所以我想要一本像

{Wienerberger AG', '4.38 Dollars', '2607606784 Billion Dollars} or {EPR Properties', '31.62 Dollars', '246636006 million Dollars}

解决方案

我在您的代码中修改了两件事：

  1. 价值压缩
  2. 返回函数

代码：

    import requests
    import pprint
    import json
    url = "https://yahoo-finance15.p.rapidapi.com/api/yahoo/ga/topgainers"
    querystring = {"start":"0"}
    headers = {'x-rapidapi-host': "yahoo-finance15.p.rapidapi.com",'x-rapidapi-key': "9efd0f3e52mshd859f5daf34a429p11cb2ajsn2b0e421d681e"}
    response = requests.request("GET", url, headers=headers, params=querystring)
    data = response.json()
    def new_stock(data):
        new_market = []
        for item in data ['quotes']:
            new_name = item.get ('longName')
            new_price = item.get ('regularMarketPrice')
            res_price = (f'{new_price} Dollars')
            cap =item.get('marketCap')
            cap2 = int(cap)        
            if cap2>=1000000000:
                cap2 = f'{cap2} Billion Dollars'
            else:
                cap2 = f'{cap2} million Dollars'
            new_market.append((new_name, res_price, cap2))
        return new_market
    value = new_stock(data)
    dict = {i: value[i] for i in range(0, len(value))}
    print(dict)

输出：
