如何使用BeautifulSoup仅提取某些字段

Question

我正在尝试打印所有包含英格兰的字段，当前代码已为我将所有国籍打印到txt文件中，但是我只想打印英格兰字段。我从中拉出的页面是https://www.premierleague.com/players

import requests
from bs4 import BeautifulSoup

r=requests.get("https://www.premierleague.com/players")
c=r.content
soup=BeautifulSoup(c, "html.parser")
players = open("playerslist.txt", "w+")


for playerCountry in soup.findAll("span", {"class":"playerCountry"}):
    players.write(playerCountry.text.strip())
    players.write("\n")

Answer 1

只需检查它是否不等于“英格兰”，如果是，则跳到列表中的下一项：

mail()

Answer 2

或者，您可以只使用pandas.read_html()和几行代码：

import pandas as pd

df = pd.read_html("https://www.premierleague.com/players")[0]
print(df.loc[df['Nationality'] != 'England'])

打印：
