python - 格式化 BeautifulSoup 的输出

Question

通过阅读 BeautifulSoup 文档，我设法编写了一个简短的 python 脚本来抓取表格并打印它，但是我不知道如何将其格式化为表格。最终目标是从网站获取足球比赛预测:https://afootballreport.com/predictions/over-1.5-goals/并将它们保存到文本文件中。

这是我到目前为止编写的代码:

import urllib
import urllib.request
from bs4 import BeautifulSoup

def make_soup(url):
    thepage = urllib.request.urlopen(url)
    soupdata = BeautifulSoup(thepage, "html.parser")
    return soupdata

soup = make_soup("https://afootballreport.com/predictions/over-1.5-goals/")
for record in soup.findAll('tr'):

    for data in record.findAll('td'):

     print(data.text.strip())

这是输出:

03/28
17:30
Iceland Reykjavik Youth Cup


Fjölnir / Vængir U19
Valur / KH U19
Over 1.5
Valur / KH U19 have over 1.5 goals in 100% of their games in the last 2 months (total games 6).
03/28
17:30
Saudi Arabia Pro League


Al Ittifaq
Al Quadisiya
Over 1.5
Al Ittifaq have over 1.5 goals in 100% of their games in the last 2 months (total games 8).

我希望它每行都有一列:日期、时间、足球联赛、主队、客队、提示、描述。像这样:

Date, Time, Football League, HomeTeam, AwayTeam, Tip, Description
03/28, 17:30, Iceland Reykjavik Youth Cup, Fjölnir / Vængir U19, Valur / KH U19, Over 1.5, Valur / KH U19 have over 1.5 goals in 100% of their games in the last 2 months (total games 6).

有人可以帮助我吗？

你做了很多工作。每当我看到 <table>标签，我首先尝试 pandas' .read_html() 。它会为您完成大部分工作，然后您可以根据需要操作数据框。

import pandas as pd

tables = pd.read_html('https://afootballreport.com/predictions/over-1.5-goals/')
table = tables[0]

table[['Date', 'Time']] = table['Home team - Away team'].str.split('  ', expand=True)
table = table.drop(['Home team - Away team'],axis=1)
table =  table.rename(columns={"Unnamed: 3":"Description"})   


table[['Football League', 'Home Team', 'Away Team']] = table['Tip'].str.split('  ', expand=True)
table = table.drop(['Tip'],axis=1)

输出:

print (table.head(5).to_string())

编辑:

如果您使用的是 Pandas 版本 0.24.2

import pandas as pd

tables = pd.read_html('https://afootballreport.com/predictions/over-1.5-goals/')
table = tables[0]

table[['Date', 'Time']] = table['Home team - Away team'].str.split('  ', expand=True)
table = table.drop(['Home team - Away team'],axis=1)
table =  table.rename(columns={"Logic":"Description"})   


table[['Football League', 'Home Team', 'Away Team']] = table['Home team - Away team.1'].str.split('  ', expand=True)
table = table.drop(['Home team - Away team.1'],axis=1)
