Ich habe diese Webseite: http://waterdata.usgs.gov/nwis/wys_rpt?dd_parm_cds=002_00060&wys_water_yr=2015&site_no=06935965Schöne Suppe wird nicht voll Tisch zurückkehrt in von HTML-Objekt
Dass ich diese Informationen von schaben hatte gehofft:
Die Informationen in gespeichert sind eine Tabelle hier, erweitert die ersten beiden Reihen, nachdem die Titel zeigt:
Also habe ich ein wenig BeautifulSoup eingerichtet und gelernt, und finde meine Tabelle (es ist die letzte auf der Seite, also die tables[-1]), aber es wird nicht die gesamte Tabelle aufnehmen - es stoppt nach dem 'Annual total' Zeilennamen/Eintrag .
Code:
from bs4 import BeautifulSoup
import requests
base_url = 'http://waterdata.usgs.gov/nwis/wys_rpt?dd_parm_cds=002_00060&wys_water_yr=2015&site_no='
site = '06935965'
url = base_url + site
r = requests.get(url)
soup = BeautifulSoup(r.text,'html.parser')
tables = soup.find_all('table')
table = tables[-1]
print(table.text)
Ausgang:
SUMMARY STATISTICS
Water Year 2015
Water Years 2000 - 2015
Annual total
Und das ist alles! Die gesamte Tabelle wird aufrufen, indem die Anfragen abgeholt:
<table class='tables'>
