我需要从在BeautifulSoup中解析的四个字符串中提取数据。它们是:
Arkansas72.21:59 AM76.29:04 AM5.22977.37:59 AM
Ashley71.93:39 AM78.78:59 AM0.53678.78:59 AM
Bradley72.64:49 AM77.28:59 AM2.41877.28:49 AM
Chicot-40.19:04 AM-40.19:04 AM2.573-40.112:09 AM
例如,第一个字符串中的数据是Arkansas、72.1、1:59 AM、76.2、9:04 AM、5.2、29、77.3和7:59 AM。有没有简单的方法?你知道吗
编辑:完整代码
import urllib2
from bs4 import BeautifulSoup
import time
def scraper():
#Arkansas State Plant Board Weather Web data
url1 = 'http://170.94.200.136/weather/Inversion.aspx'
#opens url and parses HTML into Unicode
page1 = urllib2.urlopen(url1)
soup1 = BeautifulSoup(page1, 'lxml')
#print(soup.get_text()) gives a single Unicode string of relevant data in strings from the url
#Without print(), returns everything in without proper spacing
sp1 = soup1.get_text()
#datasp1 is the chunk with the website data in it so the search for Arkansas doesn't return the header
#everything else finds locations for Unicode strings for first four stations
start1 = sp1.find('Today')
end1 = sp1.find('new Sys.')
datasp1 = sp1[start1:end1-10]
startArkansas = datasp1.find('Arkansas')
startAshley = datasp1.find('Ashley')
dataArkansas = datasp1[startArkansas:startAshley-2]
startBradley = datasp1.find('Bradley')
dataAshley = datasp1[startAshley:startBradley-2]
startChicot = datasp1.find('Chicot')
dataBradley = datasp1[startBradley:startChicot-2]
startCleveland = datasp1.find('Cleveland')
dataChicot = datasp1[startChicot:startCleveland-2]
print(dataArkansas)
print(dataAshley)
print(dataBradley)
print(dataChicot)
您需要使用beautifulsoup解析html页面并检索数据:
该示例将显示:
只要改进提取表格数据的方法。我会使用^{} 将其读入数据帧,我很肯定,您会发现使用它很方便:
