内部for循环不会跟随外部for循环

Question

外部循环会根据marketid抓取多个URL。每个URL都包含有关赛马的信息。此信息包括赔率。我想在每场比赛中附加最大的赔率。例如，如果赛马的赔率是$ 2.5，$ 3.5，$ 10，$ 36和$ 101，我想附加$ 101。我的问题是，当我将赔率附加到“数据”时，所有URL的所有赔率都将附加。这意味着它将找到所有种族而不是每个种族的最大值。如果内部循环紧随外部循环，则不会发生。

import requests
import datetime
import pandas as pd 
startdate = datetime.date(2020, 0o1, 0o1)
enddate = datetime.date(2020, 0o1, 0o2)
daycount = (enddate - startdate).days
date = startdate
marketids = []
for i in range(daycount):
    date += datetime.timedelta(days=1)
    request1 = requests.get('https://betfair-data-supplier-prod.herokuapp.com/api/daily_racing_results?date='+str(date))
    json1 = request1.json()
    for market in json1:
        if market['raceType'] in ['R']:
            for id in market['markets']:
                marketids.append(market["markets"][0]["marketId"])
data = []
for marketid in marketids:
    request2 = requests.get(f'https://betfair-data-supplier-prod.herokuapp.com/api/race_results/?market_id=1.{marketid}&nz_tote_event_id=',
    headers={'User-Agent': 'Mozilla/5.0'})
    json2 = request2.json()
    for runner in json2['runners']:
        for market in runner['markets']:
            if market.get('productType') == 'WIN_ODDS_BSP':
                data.append(market.get('price'))
                max = 0
                for d in data:
                    if d>max:
                        max = d
print(max)

这是json的示例：
