Chapter 1: Introduction to Wikipedia Data Exploration

Exploring Wikipedia data using Python can be an exciting venture! If you're looking to integrate Wikipedia information into your web applications, the MediaWiki API is a great resource. But what if there was a Python library that simplifies this process?

Installation Process

You can easily install the library in your project directory using the terminal with the following command:

$ pip install wikipedia

Once installed, you can import the library into your project like this:

import wikipedia

Performing Searches on Wikipedia

To search for a specific topic on Wikipedia, utilize the search method as follows:

print(wikipedia.search("India", results=3, suggestion=False))

This will yield the top three results for the query "India."

When the suggestion argument is set to True, it will return a tuple containing the results and any suggestions if available:

print(wikipedia.search("India", results=3, suggestion=True))

#### Summarizing Wikipedia Articles

To obtain a summary of a Wikipedia article, you can use the summary method:

print(wikipedia.summary("Python programming"))

This will output a concise summary about Python programming, highlighting its main features and characteristics.

You can tailor the output using parameters like sentences (for a specific number of sentences) or char (for a specific number of characters):

print(wikipedia.summary("Led Zeppelin", sentences=3))

Accessing Full Wikipedia Pages

If you want to retrieve data from a complete Wikipedia page, use the page method as shown below:

london_page = wikipedia.page("London")

This will load the content of the "London" Wikipedia page into a variable named london_page. You can access the title and content like this:

print(london_page.title)

print(london_page.content)

To retrieve all images related to the page, simply call:

print(london_page.images)

Handling Common Exceptions

#### DisambiguationError

If you attempt to summarize a term that leads to a disambiguation page, you will encounter a DisambiguationError. Here's how to manage it:

try:

print(wikipedia.summary("Python", sentences=3))

except wikipedia.exceptions.DisambiguationError:

print('DisambiguationError')

#### PageError

This error occurs when your search does not match any Wikipedia page. You can handle it like so:

try:

wikipedia.page("asdflkj")

except wikipedia.exceptions.PageError:

print("Your query didn't match a page on Wikipedia")

Supporting Wikipedia

Don't forget to support Wikipedia by donating! You can do this through the following command, which directs you to the Wikimedia donation page:

wikipedia.donate()

The first video titled "Low Level Data Extraction from Wikipedia Data with Python" provides an insightful look into extracting data from Wikipedia using Python, demonstrating practical techniques.

The second video, "How to Use Wikipedia API for NLP Projects," elaborates on leveraging the Wikipedia API for natural language processing tasks, making it a valuable resource for developers.
