Pip command: This keyword refers to the Python package management system that allows users to install, upgrade and manage software packages on their systems.

Getting Data from Wikipedia Module

After installing the Wikipedia module, you can start fetching data from Wikipedia pages. There are several methods available that allow users to retrieve data from Wikipedia pages.

Some of the primary methods include:

Getting random page names

The Wikipedia module provides a method that returns a random title from the Wikipedia pages. The method is called random, and it can be used as follows:

import wikipedia

title = wikipedia.random()

print(title)

The above code prints out a random title from the Wikipedia pages. This method is useful when you are looking for new and interesting topics to explore.

Getting the summary of a page

The Wikipedia module also provides a method that retrieves the summary of a Wikipedia page. The method is called summary, and it takes two parameters: the title of the Wikipedia page and the number of sentences you want in the summary.

import wikipedia

page = wikipedia.page(‘Python (programming language)’)

summary = page.summary

# Prints the first three sentences of the summary

print(summary[:summary.index(‘.’)+1])

print(summary[summary.index(‘.’)+2:summary.index(‘.’,summary.index(‘.’)+1)+1])

print(summary[summary.index(‘.’,summary.index(‘.’)+1)+2:summary.index(‘.’,summary.index(‘.’)+2)+1])

The above code retrieves the summary of the Python programming language Wikipedia page and prints the first three sentences of the summary. The output of this code is:

Python is an interpreted, high-level, general-purpose programming language.

Created by Guido van Rossum and first released in 1991, Python’s design philosophy emphasizes code readability with its notable use of significant whitespace. Its language constructs and object-oriented approach aim to help programmers write clear, logical code for small and large-scale projects.

Getting the whole Wikipedia page

The Wikipedia module also provides a function that retrieves the whole Wikipedia page. The function is called page, and it takes the title of the Wikipedia page as a parameter.

import wikipedia

page = wikipedia.page(‘Python (programming language)’)

content = page.content

# Prints the first 500 characters of the content

print(content[:500])

The above code retrieves the whole Python programming language Wikipedia page and prints the first 500 characters of the content. This method is useful when you want to extract all the information from a Wikipedia page.

Conclusion

In this article, we have explored the Wikipedia module in Python, focusing on its functionality and purpose, installing and importing it, and getting data from Wikipedia pages using it. We have looked at retrieving random page names, summaries, and the whole Wikipedia page.

These methods are useful when you want to retrieve information from Wikipedia pages that you can use in your programs. With the knowledge gained from this article, you are now equipped to start fetching data from Wikipedia pages using the Wikipedia module in Python.

Getting data in a different language using the Wikipedia module in Python is a valuable feature for multilingual programmers or those who need to extract information from Wikipedia pages in different languages. In this article, we will explore the functionality of the set_lang function in the Wikipedia module, which enables users to retrieve data in different languages from Wikipedia pages.

We will look at how to use the set_lang function and what parameters are required to retrieve information in the desired language.

Using set_lang function to get data in a different language

By default, the Wikipedia module retrieves data in English. However, it is possible to retrieve data in different languages using the set_lang function.

The set_lang function takes a string parameter that specifies the language you want to fetch information in. For example, if you want to retrieve information in French, you would pass ‘fr’ as the parameter to the set_lang function before calling other functions.

The code snippet below demonstrates how to use the set_lang function to retrieve data in French. In this example, we first import the Wikipedia module in Python and then set the language to French using the set_lang function.

Next, we retrieve the summary of the ‘Fruits’ Wikipedia page in French using the summary function. “`

import wikipedia

# Set language to French

wikipedia.set_lang(‘fr’)

# Retrieve the summary of Fruits Wikipedia page

summary = wikipedia.summary(‘Fruits’)

# Print the summary

print(summary)

“`

The output of the above code is the summary of the French Wikipedia page for fruits:

“`

Les fruits sont l’ensemble des organes d’une plante fleurs qui contient les graines ou les noyaux, l’exception de ceux des crales. Les fruits d’une plante sont souvent utiliss afin de propager les graines de cette mme plante, pour cette raison, les botanistes les classent comme des fruits.

Les fruits ont une grande importance dans l’alimentation humaine, car ils reprsentent une source importante de vitamines, de nutriments et d’antioxydants. “`

As you can see, the code successfully retrieved the summary of the fruits Wikipedia page, but in French.

The set_lang function also accepts other language codes, such as ‘es’ for Spanish, ‘de’ for German, ‘ja’ for Japanese, ‘ko’ for Korean, and so on. You can find a list of supported languages and their respective codes on the Wikipedia module documentation page.

It is important to note that not all Wikipedia pages may be available in a specific language. If the page does not exist in the specified language, the Wikipedia module will return an error message.

Additionally, if the page does exist in the specified language, but the summary is not available, the Wikipedia module will return the first section of the article instead. In addition to retrieving summaries, you can also use the set_lang function to retrieve the full Wikipedia page in a different language.

The page function works the same as before, but you pass the language code parameter to the set_lang function before calling the page function. For example:

“`

import wikipedia

# Set language to Spanish

wikipedia.set_lang(‘es’)

# Retrieve the full Wikipedia page for ‘Espaa’

page = wikipedia.page(‘Espaa’)

# Print the title and content of the page

print(‘Title:’, page.title)

print(‘Content:’, page.content)

“`

The output of the above code is, as expected, the full Wikipedia page for Spain in Spanish:

“`

Title: Espaa

Content: Espaa (AFI: [espaa]…

“`

Conclusion

The set_lang function is a valuable feature of the Wikipedia module that enables programmers to retrieve data in different languages from Wikipedia pages. The set_lang function takes a language code parameter, such as ‘fr’ for French or ‘es’ for Spanish, and allows users to retrieve summaries or full pages of Wikipedia articles.

This feature is useful for programmers who need to extract information from Wikipedia pages in different languages, and it expands the functionality of the Wikipedia module in Python to non-English speaking users. In this article, we explored the Wikipedia module in Python featured the set_lang function that enables users to retrieve data from Wikipedia pages in different languages.

The set_lang function is a powerful tool that allows programmers to conduct research in various languages, making it useful for multilingual programmers and non-English speakers. By setting the language parameter properly, you can extract information in your target language, including summaries and full pages.

The Wikipedia module is a powerful addition to any Python programmers toolkit and provides an easy method to fetch and process information from the world’s largest encyclopedia.
