我试图从一个网站刮大学的名称和地址：https://www.collegenp.com/2-science-colleges/，但问题是，我只得到了列表中的前11所大学的数据，而没有得到其他大学的数据.我已经尝试了我所知道的一切.但没有方法工作.
我的代码是：

from selenium import webdriver
import bs4
from bs4 import BeautifulSoup
import requests
import pandas as pd
from time import sleep
driver=webdriver.Chrome('C:/Users/acer/Downloads/chromedriver.exe')
driver.get('https://www.collegenp.com/2-science-colleges/')
driver.refresh()
sleep(20)
page=requests.get("https://www.collegenp.com/2-science-colleges/")
college = []
location=[]
soup= BeautifulSoup(page.content,'html.parser')
for a in soup.find_all('div',attrs={'class':'media'}):
  name=a.find('h3',attrs={'class':'college-name'})
  college.append(name.text)
  loc=a.find('span',attrs={'class':'college-address'})
  location.append(loc.text)
df=pd.DataFrame({'College name':college,'Locations':location})
df.to_csv('hell.csv',index=False,encoding='utf-8')

字符串
有没有什么方法可以让我把所有的数据都 * 出来？

您可以使用此代码从下一页获取信息：

import requests
from bs4 import BeautifulSoup
import pandas as pd
url = "https://www.collegenp.com/2-science-colleges/"
headers = {"X-Requested-With": "XMLHttpRequest"}
data = {"state": "on", "action": "filter", "count": "0"}
all_data = []
for page in range(0, 5):  # <-- increase number of pages here
    print("Getting page {}..".format(page))
    data["count"] = page * 10
    soup = BeautifulSoup(
        requests.post(url, data=data, headers=headers).content,
        "html.parser",
    )
    for c in soup.select(".college-name"):
        all_data.append(
            {
                "College name": c.get_text(strip=True),
                "Location": c.find_next(class_="college-address").get_text(
                    strip=True
                ),
            }
        )
df = pd.DataFrame(all_data)
print(df)
df.to_csv("data.csv", index=False)
