刮网球结果，包括每场比赛的比赛

Question

我想从 this website 抓取网球比赛结果

我想要的结果表有以下列：tournament_name match_time player_1 player_2 player_1_score player_2_score

这是一个例子

tournament_name      match_time   player_1           player_2               p1_set1   p2_set1
Roma / Italy         11:00        Krajinovic Filip   Auger Aliassime Felix  6         4
Iasi (IX) / Romania  10:00        Bourgue Mathias    Martineau Matteo       6         1

我无法将id="main_tour" 上的每个锦标赛名称与每一行相关联（一行是 2 个class="match" 或 2 个class="match1"

我试过这段代码：

import requests
from bs4 import BeautifulSoup

u = "http://www.tennisprediction.com/?year=2020&month=9&day=14"

headers = {'User-Agent': 'Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:76.0) Gecko/20100101 Firefox/76.0'}
session = requests.Session()
r = session.get(u, timeout=30, headers=headers)
# print(r.status_code)
soup = BeautifulSoup(r.content, 'html.parser')

for table in soup.select('#main_tur'):
    tourn_value = [i.get_text(strip=True) for i in table.select('tr:nth-child(1)')][0].split('/')[0].strip()
    tourn_name = [i.get_text(strip=True) for i in table.select('tr td#main_tour')]
    row = [i.get_text(strip=True) for i in table.select('.match')]
    row2 = [i.get_text(strip=True) for i in table.select('.match1')]
    print(tourn_value, tourn_name)

您可以使用此脚本以您的格式将表格保存为 CSV：

import requests 
import pandas as pd
from bs4 import BeautifulSoup


url = 'http://www.tennisprediction.com/?year=2020&month=9&day=14'
soup = BeautifulSoup(requests.get(url).content, 'html.parser')

all_data = []
for t in soup.select('.main_time'):
    p1 = t.find_next(class_='main_player')
    p2 = p1.find_next(class_='main_player')
    tour = t.find_previous(id='main_tour')
    scores1 = {'player_1_set{}'.format(i): s for i, s in enumerate((tag.get_text(strip=True) for tag in t.parent.select('.main_res')), 1)}
    scores2 = {'player_2_set{}'.format(i): s for i, s in enumerate((tag.get_text(strip=True) for tag in t.parent.find_next_sibling().select('.main_res')), 1)}
    all_data.append({
        'tournament_name': ' / '.join( a.text for a in tour.select('a') ),
        'match_time': t.text,
        'player_1': p1.get_text(strip=True, separator=' '),
        'player_2': p2.get_text(strip=True, separator=' '),
    })
    all_data[-1].update(scores1)
    all_data[-1].update(scores2)

df = pd.DataFrame(all_data)
df.to_csv('data.csv')
print(df)

保存data.csv：

编辑：为两个玩家添加奇数、概率列：

import requests 
import pandas as pd
from bs4 import BeautifulSoup


url = 'http://www.tennisprediction.com/?year=2020&month=9&day=14'
soup = BeautifulSoup(requests.get(url).content, 'html.parser')

all_data = []
for t in soup.select('.main_time'):
    p1 = t.find_next(class_='main_player')
    p2 = p1.find_next(class_='main_player')
    tour = t.find_previous(id='main_tour')
    odd1 = t.find_next(class_='main_odds_m')
    odd2 = t.parent.find_next_sibling().find_next(class_='main_odds_m')
    prob1 = t.find_next(class_='main_perc')
    prob2 = t.parent.find_next_sibling().find_next(class_='main_perc')
    scores1 = {'player_1_set{}'.format(i): s for i, s in enumerate((tag.get_text(strip=True) for tag in t.parent.select('.main_res')), 1)}
    scores2 = {'player_2_set{}'.format(i): s for i, s in enumerate((tag.get_text(strip=True) for tag in t.parent.find_next_sibling().select('.main_res')), 1)}
    all_data.append({
        'tournament_name': ' / '.join( a.text for a in tour.select('a') ),
        'match_time': t.text,
        'player_1': p1.get_text(strip=True, separator=' '),
        'player_2': p2.get_text(strip=True, separator=' '),
        'odd1': odd1.text,
        'prob1': prob1.text,
        'odd2': odd2.text,
        'prob2': prob2.text
    })
    all_data[-1].update(scores1)
    all_data[-1].update(scores2)

df = pd.DataFrame(all_data)
df.to_csv('data.csv')
print(df)

Andrej 的解决方案非常漂亮和优雅。接受他的解决方案，但这是我的尝试：

import requests
from bs4 import BeautifulSoup
import pandas as pd



url = 'http://www.tennisprediction.com/?year=2020&month=9&day=14'
response = requests.get(url)

soup = BeautifulSoup(response.text, 'html.parser')


rows=[]
for matchClass in ['match','match1']:
    matches = soup.find_all('tr',{'class':'match'})
    for idx, match in enumerate(matches):
        if idx%2 != 0:
            continue
        row = {}
        tourny = match.find_previous('td',{'id':'main_tour'}).text
        time = match.find('td',{'class':'main_time'}).text
        p1 = match.find('td',{'class':'main_player'})
        player_1 = p1.text
        row.update({'tournament_name':tourny,'match_time':time,'player_1':player_1})
        
        sets = p1.find_previous('tr',{'class':'match'}).find_all('td',{'class':'main_res'})
        for idx,each_set in enumerate(sets):
            row.update({'p1_set%d'%(idx+1):each_set.text})
            
        p2 = match.find_next('td',{'class':'main_player'})
        player_2 = p2.text
        row.update({'player_2':player_2})
        sets = p2.find_next('tr',{'class':'match'}).find_all('td',{'class':'main_res'})
        for idx,each_set in enumerate(sets):
            row.update({'p2_set%d'%(idx+1):each_set.text})
        rows.append(row)
     
df = pd.DataFrame(rows)

输出：

print(df.head(10).to_string())
                                    tournament_name match_time                                player_1 p1_set1 p1_set2 p1_set3 p1_set4 p1_set5                                player_2 p2_set1 p2_set2 p2_set3 p2_set4 p2_set5
