Today lets look at scraping Yellow pages data using Beautiful soup and the requests module in python. Here is a simple script that does that. BeautifulSoup will help us extract information and we.

These class names were found using Developer Tools; The time function has been used to be easy on the website this time:) Flattening List of Lists. We will discuss the different installation options available for Beautiful Soup in different operating systems, such as Linux, Windows, and Mac OS X. The Python version that we are going to use in the later examples for installing Beautiful Soup is Python 2.7.5 and the instructions for Python 3 are probably different. I have tried everything here: How can I install the Beautiful Soup module on the Mac? Installation seems to work (getting correct output during install) from both the traditional way to install an.


As BeautifulSoup is not a standard python library, we need to install it first. We are going to install the BeautifulSoup 4 library (also known as BS4), which is the latest one.

To isolate our working environment so as not to disturb the existing setup, let us first create a virtual environment.

Creating a virtual environment (optional)

A virtual environment allows us to create an isolated working copy of python for a specific project without affecting the outside setup.

Best way to install any python package machine is using pip, however, if pip is not installed already (you can check it using – “pip –version” in your command or shell prompt), you can install by giving below command −

Linux environment

Windows environment

To install pip in windows, do the following −

  • Download the get-pip.py from https://bootstrap.pypa.io/get-pip.py or from the github to your computer.

  • Open the command prompt and navigate to the folder containing get-pip.py file.

  • Run the following command −

That’s it, pip is now installed in your windows machine.

You can verify your pip installed by running below command −

Installing virtual environment

Run the below command in your command prompt −

After running, you will see the below screenshot −

Below command will create a virtual environment (“myEnv”) in your current directory −

Screenshot

To activate your virtual environment, run the following command −

In the above screenshot, you can see we have “myEnv” as prefix which tells us that we are under virtual environment “myEnv”.

To come out of virtual environment, run deactivate.

As our virtual environment is ready, now let us install beautifulsoup.

Installing BeautifulSoup

As BeautifulSoup is not a standard library, we need to install it. We are going to use the BeautifulSoup 4 package (known as bs4).

Linux Machine

To install bs4 on Debian or Ubuntu linux using system package manager, run the below command −

You can install bs4 using easy_install or pip (in case you find problem in installing using system packager).

(You may need to use easy_install3 or pip3 respectively if you’re using python3)

Windows Machine

To install beautifulsoup4 in windows is very simple, especially if you have pip already installed.

So now beautifulsoup4 is installed in our machine. Let us talk about some problems encountered after installation.

Problems after installation

On windows machine you might encounter, wrong version being installed error mainly through −

  • error: ImportError “No module named HTMLParser”, then you must be running python 2 version of the code under Python 3.

  • error: ImportError “No module named html.parser” error, then you must be running Python 3 version of the code under Python 2.

Best way to get out of above two situations is to re-install the BeautifulSoup again, completely removing existing installation.

If you get the SyntaxError “Invalid syntax” on the line ROOT_TAG_NAME = u’[document]’, then you need to convert the python 2 code to python 3, just by either installing the package −

or by manually running python’s 2 to 3 conversion script on the bs4 directory −

Installing a Parser

By default, Beautiful Soup supports the HTML parser included in Python’s standard library, however it also supports many external third party python parsers like lxml parser or html5lib parser.

To install lxml or html5lib parser, use the command −

Linux Machine

Windows Machine

Generally, users use lxml for speed and it is recommended to use lxml or html5lib parser if you are using older version of python 2 (before 2.7.3 version) or python 3 (before 3.2.2) as python’s built-in HTML parser is not very good in handling older version.

Running Beautiful Soup

It is time to test our Beautiful Soup package in one of the html pages (taking web page – https://www.tutorialspoint.com/index.htm, you can choose any-other web page you want) and extract some information from it.

In the below code, we are trying to extract the title from the webpage −

Output

One common task is to extract all the URLs within a webpage. For that we just need to add the below line of code −

Output

Similarly, we can extract useful information using beautifulsoup4.

Now let us understand more about “soup” in above example.

Beautiful Soup is a Python library for pulling data out of HTML and XML files. It works with your favorite parser to provide idiomatic ways of navigating, searching, and modifying the parse tree. It commonly saves programmers hours or days of work. Latest Version of Beautifulsoup is v4.8.2 as of now.
