我正在尝试抓取一个名为WikiCFP的网站，并将表中的信息作为数据框架返回。现在我有这个代码
import requests
from bs4 import BeautifulSoup
import pandas as pd
import re
df = pd.DataFrame(columns=["abbreviation", "name", "dates", "place", "deadline"])
url = "http://www.wikicfp.com/cfp/call?conference=computer%20science&page=1"
response = requests.get(url)
soup= BeautifulSoup(response.content, "html.parser")
table = soup.find("table", align="center",cellpadding="3",cellspacing="1",width="100%")
for row in table.find_all("tr")[1:]:
values= row.find_all("td")
print(values[0].text.split("/n")[0])
我特别不知道如何将每行中的文本转换为可行的列表或其他一些可以制作数据框架的东西。提前感谢
您可以直接使用read_html:
dfs = pd.read_html(url, header=0) # return all tables in a list of dataframe
df = dfs[4] # 4 is the index of the dataframe you want
输出:
>>> df
