【问题描述】：

这是我previous problem的后续问题

driver = webdriver.Chrome(executable_path="C:/Users/Joonas/PycharmProjects/Dictionaries/chromedriver.exe")
driver.get("http://naturalstattrick.com/games.php")
driver.minimize_window()
away_team = driver.find_element_by_xpath("//*[@id='teams_wrapper']/div[2]/div[3]/div[2]/div/table/tbody/tr[1]/td[2]") #Arizona
home_team = driver.find_element_by_xpath("//*[@id='teams_wrapper']/div[2]/div[3]/div[2]/div/table/tbody/tr[2]/td[2]") #Vegas
print(away_team.text, home_team.text)

输出：

Arizona Coyotes Vegas Golden Knights

我想循环上面提到的字符串，以便在每次循环后（游戏）/tr[] 发生变化。下一场比赛球队的字符串如下：

"//*[@id='teams_wrapper']/div[2]/div[3]/div[2]/div/table/tbody/tr[3]/td[2]" #Chicago
"//*[@id='teams_wrapper']/div[2]/div[3]/div[2]/div/table/tbody/tr[4]/td[2]" #Washington

我正在尝试构建一个程序，当我运行该程序时，它会抓取所有游戏并在各自的行上分别打印每个游戏：

Game1 away team Game1 home team
Game2 away team Game2 home team
Game3 away team Game3 home team

预期输出：

Arizona Coyotes Vegas Golden Knights
Chicago Blackhawks Washington Capitals
etc....

【解决方案1】：

试试这个：

team_string = "//*[@id='teams_wrapper']/div[2]/div[3]/div[2]/div/table/tbody/tr[1]/td[2]"
all_team_list = [team_string[:65]+str(i+1)+team_string[66:] for i in range(0,15)] # Change 15 to 107/109
team_text = [driver.find_element_by_xpath(i).text for i in all_team_list]
team_text = zip(*[team_text[i::2] for i in range(2)])
print(*[f'Game {i+1} away team : {awt}, home team : {hmt}' for i, (awt, hmt) in enumerate(team_text)], sep='\n')

输出：

Game 1 away team : Arizona Coyotes, home team : Vegas Golden Knights
Game 2 away team : Chicago Blackhawks, home team : Washington Capitals
Game 3 away team : Dallas Stars, home team : St Louis Blues
Game 4 away team : Boston Bruins, home team : New Jersey Devils
Game 5 away team : Calgary Flames, home team : Vancouver Canucks
Game 6 away team : Montreal Canadiens, home team : New Jersey Devils
Game 7 away team : New York Islanders, home team : Philadelphia Flyers
