How using Python3 with BeautifulSoup get an article's text from Wikipedia

I have such script made in Python3:

response = simple_get("https://en.wikipedia.org/wiki/Mathematics")

result = {'url': url}

if response is not None:

    html = BeautifulSoup(response, 'html.parser')

    title = html.select("#firstHeading")[0].text

As you can see I can get the title from the article, But I can not figure out how to get text from "Mathematics" (from Greek μά...) to the contents table...

select the <p> tag. There are 52 elements. Not sure if you want the whole thing, but you can iterate through those tags to store it as you may. I just chose to print each of them to show the output.

import bs4

import requests





response = requests.get("https://en.wikipedia.org/wiki/Mathematics")



if response is not None:

    html = bs4.BeautifulSoup(response.text, 'html.parser')



    title = html.select("#firstHeading")[0].text

    paragraphs = html.select("p")

    for para in paragraphs:

        print (para.text)



    # just grab the text up to contents as stated in question

    intro = 'n'.join([ para.text for para in paragraphs[0:5]])

    print (intro)

if response is not None can be rewritten as if response. also since the content may change in the future I would have suggested to get the entire div, read only the p and stop when you reach the div with class "toclimit-3"

@PinoSan I think it doesn't hurt to check for None explicitly. For example bool('' is not None) is not the same as bool(''). However, in this case the None check is completely unnecessary because response will always be a requests.models.Response object. If the request fails an exception will be raised.

@t.m.adam what you are saying is true but as you said the response is not a string. So you just wanted to check that it was a valid object, not an empty string, None or an empty dictionary, ... About the exceptions, I agree we should check for exceptions in case of networks errors but also we should check for status code to be 200
– PinoSan

@PinoSan Of course, and I too prefer the if response style, but you know, "Explicit is better than implicit.". The problem with if response is that it may produce strange errors, difficult to debug. But yes, in most cases a simple boolean check should be enough.

You can get the desired output using lxml library like following.

import requests

from lxml.html import fromstring



url = "https://en.wikipedia.org/wiki/Mathematics"



res = requests.get(url)

source = fromstring(res.content)

paragraph = 'n'.join([item.text_content() for item in source.xpath('//p[following::h2[2][span="History"]]')])

print(paragraph)

Using BeautifulSoup:

from bs4 import BeautifulSoup

import requests



res = requests.get("https://en.wikipedia.org/wiki/Mathematics")

soup = BeautifulSoup(res.text, 'html.parser')

for item in soup.find_all("p"):

    if item.text.startswith("The history"):break

    print(item.text)

from lxml.html import fromstring

print(paragraph)

Using BeautifulSoup:

import requests



res = requests.get("https://en.wikipedia.org/wiki/Mathematics")

soup = BeautifulSoup(res.text, 'html.parser')

for item in soup.find_all("p"):

    if item.text.startswith("The history"):break
