Question

考虑以下简单的循环，它产生我想要的输出：

import itertools as it
for e in range (0, 16):
    for i in it.chain(range(30, 53), range(1, 19)):
        print(e, i)

我构建的这段代码的扩展版本没有产生预期的结果：

import json
import requests
import time
import datetime
import dateutil
import traceback
import os.path
import itertools as it

year_map = [2,89,213,359,542,803,1208,937,2025,2539,3115,4345,5476,6531,7794,9155,5826]
tournament_map = [26,114,243,421,579,903,1291,1645,2175,2689,3419,4940,5861,6978,8273]
years = [1999,2000,2001,2002,2003,2004,2005,2006,2007,2008,2009,2010,2011,2012,2013,2014,2015]

for i in range (0, 16):

    try:

        url = ('http://www.whoscored.com/tournamentsfeed/',str(year_map[i]),'/Fixtures/')
        url = ''.join(url)
        headers = {'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/36.0.1985.125 Safari/537.36',
        'X-Requested-With': 'XMLHttpRequest',
        'Host': 'www.whoscored.com',
        'Referer': 'http://www.whoscored.com/'}

        for f in it.chain(range(30, 53), range(1, 19)):

            game_week = (str(years[i]), 'W', str(f))
            game_week = ''.join(game_week)

            params = {'d': game_week,
            'isAggregate': 'false'}

            response = requests.get(url, params=params, headers=headers)
            response2 = (url, str(params))
            response2 = ','.join(response2)

            json_data = response.content.replace("'", '"').replace(',,', ',null,')
            fixtures = json.loads(json_data)

            if len(fixtures) > 1:

                myfile = ",\n".join([", ".join(str(x) for x in fixture) for fixture in fixtures])  # `fixtures` is a nested list
                print myfile
                myfile2 = myfile + '\n'
                time.sleep(20)

                #create text file here


    except Exception as exc:

        print response2
        print exc
        print response.status_code
        print response.text
        pass
        time.sleep(20)

print "-" *120

当我运行此版本的代码时，它只迭代两个链式范围中的第一个。在这种情况下，生成一个季节的八月到十二月期间浏览的足球数据部分的数据。然后代码停止执行而不会出错。

任何人都可以在代码中看到导致这种情况发生的任何事情吗？我很难过。

由于

只有两个链式范围中的第一个执行
