大家好，感謝您抽出寶貴的時間來研究我的問題，我已經(jīng)在此代碼上工作了大約1周的時間（我也是編碼和python的新手，也是1周的時間）。目前，該循環(huán)僅在xrange（x）中有效和'rp'：'x'是該xml中可用的正確行數(shù)。xml全天更新，我想知道是否有人可以提供使x動態(tài)的解決方案？import mechanizeimport urllibimport jsonimport refrom sched import schedulerfrom time import time, sleepfrom sched import schedulerfrom time import time, sleeps = scheduler(time, sleep)def run_periodically(start, end, interval, func):event_time = startwhile event_time < end:    s.enterabs(event_time, 0, func, ())    event_time += intervals.run()def getData():  post_url = "urlofinterest_xml"browser = mechanize.Browser()browser.set_handle_robots(False)browser.addheaders = [('User-agent', 'Firefox')]######These are the parameters you've got from checking with the aforementioned toolsparameters = {'page' : '1',              'rp' : '8',              'sortname' : 'roi',              'sortorder' : 'desc'             }#####Encode the parametersdata = urllib.urlencode(parameters)trans_array = browser.open(post_url,data).read().decode('UTF-8')xmlload1 = json.loads(trans_array)pattern1 = re.compile('>&nbsp;&nbsp;(.*)<')pattern2 = re.compile('/control/profile/view/(.*)\' title=')pattern3 = re.compile('<span style=\'font-size:12px;\'>(.*)<\/span>')pattern4 = re.compile('title=\'Naps posted: (.*) Winners:')pattern5 = re.compile('Winners: (.*)\'><img src=')
