Invalid Argument in Open method for web scraping
I am trying to scrape some data from the ancestry, I have a .net background but thought i'd try a bit of python for a project.
I'm falling at the first step, Firstly i am trying to open this page and then just print out the rows.
from requests import get
from requests.exceptions import RequestException
from contextlib import closing
from bs4 import BeautifulSoup
raw_html = open('https://www.ancestry.co.uk/search/collections/britisharmyservice/?
birth=_merthyr+tydfil-wales-united+kingdom_1651442').read()
html = BeautifulSoup(raw_html, 'html.parser')
for p in html.select('tblrow record'):
print(p)
I am getting an illegal argument on open.
python

open
is used for files, not webpages. You probably meant to userequests.get
.

According to documentation, open
is used to:
Open [a] file and return a corresponding file object.
As such, you cannot use it for downloading the HTML contents of a webpage. You probably meant to use requests.get
as follows:
raw_html = get('https://www.ancestry.co.uk/search/collections/britisharmyservice/?
birth=_merthyr+tydfil-wales-united+kingdom_1651442').text
# .text gets the raw text of the response
# (http://docs.python-requests.org/en/master/api/#requests.Response.text)
Here are a few recommendation to improve your code as well:
requests.get
provides many useful parameters, one of them beingparams
, which allows you to provide the URL parameters in the form of a Python dictionary.- If you need to verify whether the request was successful before accessing its text, then just check if the returned
response.status_code == requests.codes.ok
. This only covers status code 200, but if you need more codes, thenresponse.raise_for_status
should be helpful.
