Question

试图弄清楚为什么我的小队功能要运行两次。靠近底部的大多数函数都将前一个函数的数据作为输入，最后一个函数在列表列表中查找最大值。我想在这里正确设置我的主设备，以便1）在该程序中一切正常运行，以及2）从另一个程序调用时，它将仅自行运行小队并将小队的值返回给该程序

在我的外队看来，小队跑了两次，而循环打印了“一次完成”-两次。话虽如此，我应该如何设置主电源？

这是如何工作的-

第一个函数小队返回列表列表
第二个函数Goals_convert_dash-从第一个函数（小队）获取输出-在列表列表中获取两个元素（每个列表），如果有破折号（-），则将其转换为零。。第三功能-Goal_convert_toint从Goals_convert_dash获取输出并将第二列转换为零。
第四-get_max然后从第二列获取最大值，并将其与第一列零的数据一起输出

如果运行正常，我认为输出应该是-

一次完成英超联赛最佳进球手是： ['John Smith'，11]

我当前的输出是-

iter one done
Premier league top goal scorer is: 
['John Smith', 11]
iter one done

程序-

import requests

from scrape1_squad_urls import table

# Squad Data

    strip_team_name = [i.replace('https://www.someurl.com', '') for i in team_table]
    full_strip = [i.replace('-squad', '') for i in strip_team_name]

    iter = 0
    while iter < 1:
        tdstrip = []
        x = []
        tdstripclean = []
        for i in team_table:


                squad_r = requests.get(i)

                now = datetime.datetime.now()
                soup = BeautifulSoup(squad_r.text, 'html.parser')

        #       div = soup.find('div', {'class': '-bp30-box col span1/1'})

                full_strip = [i.replace('-squad', '') for i in strip_team_name]
                find_team_name = soup.find('span',{'class': 'swap-text__target'})
                for table in premier_squad_table:

                        td = row.find_all('td')
                        x = [x.text.strip() for x in td]
                        position_teamname = (headers[0].text,find_team_name.text)
                        x[2]
                        x.extend(position_teamname)
                        tdstrip.append(x)
        iter = iter + 1
        print("iter one done")
    return(tdstrip)

#   return(newList)
#squads()

def goals_convert_dash():

    tdstrip = squads()  

    indexes = [0,2]
    newList = [[each_list[i] for i in indexes ] for each_list in tdstrip ]
    for eachlist in newList:
        if eachlist[1] == '-':
            eachlist[1] = 0
    return(newList) 
#goals_convert_dash()



#print(newList)

def goals_convert_toint():
    converted = goals_convert_dash()

    for eachlist in converted:
        eachlist[1] = int(eachlist[1])
    return(converted)        

#goals_convert_toint()


def get_max(lst, i, key_func=None):

    if not key_func: key_func = lambda x: x[i]
    res = max(lst, key=key_func)
    return [res[0], res[i]]

data = goals_convert_toint()

print("Premier league top goal scorer is: ")

print(get_max(data,1, lambda x: int(x[1])))

if __name__ == '__main__':
     squads()
#    goals_convert_dash()
#    goals_convert_toint()
#    get_max()

程序运行两次-正确使用主程序
