Decode HTML entities into Python String

In this article, we will learn to decode HTML entities into Python String. We will use some built-in functions and some custom code as well.

Let us discuss decode HTML scripts or entities into Python String. It increases the readability of the script. A programmer who does not know about HTML script can decode it and read it using Strings. So, these three methods will decode the ASCII characters in an HTML script into a Special Character.

Example: Use HTML Parser to decode HTML Entities

It imports html library of Python. It has html.unescape() function to remove and decode HTML entities and returns a Python String. It replaces ASCII characters with their original character.

import html print(html.unescape('£682m')) print(html.unescape('© 2010'))

Example: Use Beautiful Soup to decode HTML Entities

It uses BeautifulSoup for decoding HTML entities.This represents Beautiful Soup 4 as it works in Python 3.x. For versions below this, use Beautiful Soup 3. For Python 2.x, you will need to specify the convertEntities argument to the BeautifulSoup constructor. But in the case of Beautiful Soup 4, entities get decoded automatically. html.parser is passed as an argument along with the HTML script to BeautifulSoup because it removes all the extraneous HTML that wasn’t part of the original string (i.e. and ).

# Beautiful Soup 4 from bs4 import BeautifulSoup print(BeautifulSoup("£682m", "html.parser"))

Example: Use w3lib.html Library to decode HTML Entities

This method uses w3lib.html module. In order to avoid «ModuleNotFoundError«, install w3lib using pip install using the given command. It provides replace_entities to replace HTML script with Python String.

from w3lib.html import replace_entities print(replace_entities("£682m"))

Conclusion

In this article, we learned to decode HTML entities into Python String using three built-in libraries of Python such as html , w3lib.html , and BeautifulSoup . We saw how HTML script is removed and replaced with ASCII characters. Install your packages correctly if you are getting «ModuleNot FoundError«.

How to Convert HTML to Text with Python and Pandas

In this short guide, we’ll see how to convert HTML to raw text with Python and Pandas. It is also known as text extraction from HTML tags.

2. Setup

In this Python guide, we’ll use the following DataFrame, which consists of two columns. Column html contains HTML tags and text inside the tags:

import pandas as pd data = Hello", "
Use applymap
", "
Code:
 df.head()" ]> df = pd.DataFrame.from_dict(data) 

We would like to extract the raw text from the column without the HTML tags with Python:

Step 1: Install Beautiful Soup library

First we will need to install Python library — beautifulsoup4 by:

pip install beautifulsoup4 

The official documentation of the library is available on this link: Beautiful Soup Documentation.

The Beautiful Soup is described as:

Beautiful Soup is a Python library for pulling data out of HTML and XML files.

Step 2: Extract text from HTML tags by Python

Now let’s check how we can extract the text from HTML code or tags in Python. We will demonstrate the extraction in simple example.

Suppose we have the following HTML document:

html_doc = """ 
 
 

from bs4 import BeautifulSoup soup = BeautifulSoup(html_doc, 'html.parser') print(soup.get_text())

df[['html']].applymap(lambda text: BeautifulSoup(text, 'html.parser').get_text())
