10.1. Getting Data From Websites#
We have seen that read_html can get content from an actual website, not a data file that is hosted somewhere on the internet, that takes tables on a website and returns a list of DataFrames.

This gives us a list of DataFrames that come from the website. pandas gets tables by looking in the html for the site and finding the <table> tags.
10.2. Everything is Data#
For the purpose of this class, it is best to think of the content on a web page like a datastructure.
there are tags <> that define the structure, and these can be further classified with classes
10.3. Scraping a URI website#
We’re going to create a DataFrame about URI CS & Statistics Faculty.
from the people page of the department website.
We can inspect the page to check that it’s well structured.
Warning
With great power comes great responsibility.
always check the robots.txt
do not do things that the owner says not to do
government websites are typically safe
We’ll save the URL for easy use
Then we can use the requests library to make a call to the internet. It actually gets back a response object which has a lot of extra information. For today we only need the content from the page which is an attrtibute of that object
cs_people_url = 'https://web.uri.edu/cs/people/'
cs_people_html = requests.get(cs_people_url).content
cs_people = BeautifulSoup(cs_people_html,'html.parser')
This is raw:
cs_people_html[:100]
b'\n<!DOCTYPE html>\n<html lang="en-US">\n\t\n<head>\n<meta charset="UTF-8"><script type="text/javascript">('
But we do not need to manually write search tools, that’s what BeautifulSoup is for.

We notice that the name is inside a <h3> tag with class p-name and then inside an a tag after that. We also know from looking at the overall page that there are lots of other a tags, so we do not want to search all of those.
people_items[0].find('h3','p-name').a.string

Then we can use a list comprehension to build alist of them.

We can pull out two more things, the people-department indicates who is CS & who is Statistics.

10.4. Crawling and scraping#
Remember we pulled the names out of links, when in the browser, we click on the links, we see that they are to a profile page. On these pages, they have the office number. Let’s add those to our dataframe.
First, we will do it for one person, then make a loop.
people_items[0].find('h3','p-name').a
<a href="https://web.uri.edu/cs/meet/marco-alvarez/">Marco Alvarez</a>
We see that the information that we want is in the href attribute, to read that, we check the documentation. This tells us there is a .attrs attribute of the python object we are working with.
people_items[0].find('h3','p-name').a.attrs
{'href': 'https://web.uri.edu/cs/meet/marco-alvarez/'}
It’s a dictionary and the attribute we want is the key we want. Nowe, we do the same thing we did above, request, pull the content from the response and then use the parser.
alvarez_url = people_items[0].find('h3','p-name').a.attrs['href']
alvarez_html = requests.get(alvarez_url).content
alvarez_info = BeautifulSoup(alvarez_html,'html.parser')
then we find the tag and class we need from inspecting and pull that.
alvarez_info.find_all('li','people-location')
[<li class="people-location"><strong>Office Location:</strong> Tyler 255</li>]
it’s an interable, so we pull the item out
alvarez_info.find_all('li','people-location')[0]
<li class="people-location"><strong>Office Location:</strong> Tyler 255</li>
Then we get the content.
alvarez_info.find_all('li','people-location')[0].string
this time this doesn’t work, so we can use the python __dict__ to inspect the object and see where it stored what we want.
alvarez_info.find_all('li','people-location')[0].__dict__
{'parser_class': bs4.BeautifulSoup,
'name': 'li',
'namespace': None,
'_namespaces': {},
'prefix': None,
'sourceline': 371,
'sourcepos': 329,
'known_xml': False,
'attrs': {'class': ['people-location']},
'contents': [<strong>Office Location:</strong>, ' Tyler 255'],
'parent': <ul class="people-list">
<li class="people-title">Associate Professor | Director of Graduate Studies</li> <li class="people-department">Computer Science</li> <li class="people-phone"><strong>Phone:</strong> 401.874.5009</li> <li class="people-email"><strong>Email:</strong> <a href="mailto:malvarez@uri.edu">malvarez@uri.edu</a></li> <li class="people-location"><strong>Office Location:</strong> Tyler 255</li> <li class="people-url"><strong>Website:</strong> <a href="http://homepage.cs.uri.edu/~malvarez/">http://homepage.cs.uri.edu/~malvarez/</a> </li></ul>,
'previous_element': ' ',
'next_element': <strong>Office Location:</strong>,
'next_sibling': ' ',
'previous_sibling': ' ',
'hidden': False,
'can_be_empty_element': False,
'cdata_list_attributes': {'*': ['class', 'accesskey', 'dropzone'],
'a': ['rel', 'rev'],
'link': ['rel', 'rev'],
'td': ['headers'],
'th': ['headers'],
'form': ['accept-charset'],
'object': ['archive'],
'area': ['rel'],
'icon': ['sizes'],
'iframe': ['sandbox'],
'output': ['for']},
'preserve_whitespace_tags': {'pre', 'textarea'},
'interesting_string_types': (bs4.element.NavigableString, bs4.element.CData)}
it’s the second elment of content
alvarez_info.find_all('li','people-location')[0].contents[1]
' Tyler 255'
Now tht we know how to do it, we can put it in a loop.
offices = []
for name_link in cs_people.find_all('h3','p-name'):
url = name_link.a.attrs['href']
person_html = requests.get(url).content
person_info = BeautifulSoup(person_html,'html.parser')
try:
offices.append(person_info.find_all('li','people-location')[0].contents[1])
except:
offices.append(pd.NA)
css_df['office'] = offices
We got an error at first, so we added the try and except to handle when there is no office location.
css_df.head()
| name | title | e-mails | discipline | office | |

10.5. Questions after class#
10.5.1. what does .a do?#
it gives the first instance of the <a> tag
10.5.2. is it worth it to try and web scrape a page that is poorly written?#
If it is important information. In these cases, you might have to do more manual parsing or even some manual fixes.
For this class, no.
10.5.3. In theory, you could parse images and potentially their metadata with this method?#
This method could be a way to download images and the text that is around them, yes. This is how a lot of image datasets are built for machine learning.
10.5.4. Is API the website’s way of specify what information it will allow for you have?#
What we did today did not use any API. An API call would use the request library, and similar patterns to what we did, espeically the end of class. However and API call would typically respond with json, not html.
10.5.5. In the web-scraping of the offices, there were two strings, ‘CBLS 377’, and ‘CBLS Building 487’ how would we use pandas to normalize things like this?”#
We could use the replace method that we used last week.
