#pandas #web-scraping
Вопрос:
Я пытаюсь очистить веб-сайт под названием WikiCFP и вернуть информацию в таблице в виде фрейма данных. На данный момент у меня есть этот код
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 scienceamp;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])
Я конкретно не знаю, как преобразовать текст в каждой строке в жизнеспособный список или какую-то другую вещь, из которой можно создать фрейм данных.
Заранее спасибо
Ответ №1:
Вы можете использовать read_html напрямую:
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
Выходной сигнал:
>>> df
