Python，Web抓取条形图

Question

我目前正试图从这个页面上删除条形图/图表，但我不确定提取这些类型的条形图需要哪些特定的BeautifulSoup功能。此外，如果有人链接到BeautifulSoup功能用于抓取什么类型的图表/图形，我们将不胜感激https://www.statista.com/statistics/215655/number-of-registered-weapons-in-the-us-by-state/

这是我到目前为止的代码

import pandas as pd
import requests
from bs4 import BeautifulSoup

dp = 'https://www.statista.com/statistics/215655/number-of-registered-weapons-in-the-us-by-state/'
page = requests.get(dp).text
soup = BeautifulSoup(page, 'html.parser')

#This is what I am trying to figure out
new = soup.find("div", id="bar") 
print(new)

Answer 1

此脚本将从条形图中获取所有数据：

import requests
import pandas as pd
from bs4 import BeautifulSoup

url = 'https://www.statista.com/statistics/215655/number-of-registered-weapons-in-the-us-by-state/'

soup = BeautifulSoup(requests.get(url).content, 'html.parser')

tds = soup.select('#statTableHTML td')
data = []
for td1, td2 in zip(tds[::2], tds[1::2]):
    data.append({'State':td1.text, 'Number': td2.text})

df = pd.DataFrame(data)
print(df)
