如何在 beautifulsoup 中找到列表的 parents

Question

import requests
from bs4 import BeautifulSoup

url ="https://www.hltv.org/stats/matches/mapstatsid/103093/furia-vs-chaos"
headers= {"user-agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64)"}

response = requests.get(url, headers = headers)
soup = BeautifulSoup(response.content, "html.parser")
#stat_tables = soup.find_all("table", class_="stats-table")



results = {}

all_results = soup.find_all("div", class_="round-history-half")
for partial_result in all_results:
    half_results = partial_result.find_all("img")
    for result in half_results:
        if (result["title"]):
            rounds_won = result["title"].split("-")
            key = int(rounds_won[0]) + int(rounds_won[1])
            results[key] = result["title"]

for key in sorted(results):
    print(key, results[key])

这段代码给出了比赛的所有分数，我想找到 parent，让我们说打印（结果[4]），看看谁赢了。我不确定如何从列表中找到 parents。

结果应该是

<img alt="FURIA" src="https://static.hltv.org/images/team/logo/8297" class="round-history-team" title="FURIA">

或

Furia

Answer 1

使用这个，

# retrieve the parent first.
divs = soup.find_all("div", class_="round-history-team-row")

for div in divs:
    parent_img_title = div.find('img', class_="round-history-team")['title']
    print("Title : " + parent_img_title)

    for result in div.find_all("img", class_="round-history-outcome"):
        if result["title"]:
            rounds_won = result["title"].split("-")
            key = int(rounds_won[0]) + int(rounds_won[1])
            print("Key %d" % key)
            results[key] = result["title"]

输出，

Title : FURIA
Key 4
Key 5
...
Title : Chaos
Key 1
Key 2

您可能想要更改数据结构以使其更易于使用：编辑：更新了新的数据结构

import json
import requests
from bs4 import BeautifulSoup

url = 'https://www.hltv.org/stats/matches/mapstatsid/103093/furia-vs-chaos'
headers = {'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64)'}

response = requests.get(url, headers=headers)
soup = BeautifulSoup(response.content, 'html.parser')
#stat_tables = soup.find_all('table', class_='stats-table')


results = {}

# get the match root element
match = soup.find('div', class_='standard-box round-history-con')
# get all the teams in the match
teams = [team['title'] for team in match.find_all('img', class_='round-history-team')]
# get the rows in the match visualization
rows = match.find_all('div', class_='round-history-team-row')
for row in rows:
    # get the index and round element for each round
    for idx, rnd in enumerate(row.find_all('img', class_='round-history-outcome')):
        # make sure there is data in the round
        if (rnd['title']):
            # split the string
            scores = rnd['title'].split('-')
            # get the team and score, this won't work if they get out of order
            results[idx+1] = {team: score for team, score in zip(teams, scores)}


sorted_results = {i: results[i]
                  for i in sorted(results.keys())}

print(json.dumps(sorted_results, indent=4))

输出：

Answer 3

试试这个...

if team_left[0].find_all("div", class_="bold won"):
    print(team_left[0].find_all("img")[0].get("alt"))
else:
    print(team_right[0].find_all("img")[0].get("alt"))
