write a python function that given a subject, downloads a wikipedia article and saves it as pdf
Sure, I can help you with that. Here's a simple Python function that uses the Wikipedia API to fetch the content of a Wikipedia page, and then uses the pdfkit
library to convert that content into a PDF file.
Please note that you need to have wikipedia-api
and pdfkit
installed in your Python environment. If they're not installed, you can add them using pip:
pip install wikipedia-api pdfkit
Here's the Python code:
import wikipediaapi import pdfkit def wiki_to_pdf(subject): wiki_wiki = wikipediaapi.Wikipedia('en') page_py = wiki_wiki.page(subject) if page_py.exists(): content = page_py.text pdfkit.from_string(content, f'{subject}.pdf') print(f'PDF saved as {subject}.pdf') else: print(f'No Wikipedia page found for "{subject}"') # Usage wiki_to_pdf('Python (programming language)')
This function takes a subject as input, fetches the content of the corresponding Wikipedia page, and then saves that content as a PDF file. If no Wikipedia page exists for the given subject, it prints a message saying so.
ERROR: Could not find a version that satisfies the requirement wikipediaapi (from versions: none) ERROR: No matching distribution found for wikipediaapi
It seems like there's a mistake in the package name. The correct package name is wikipedia-api
, not wikipediaapi
.
You can install it using the following command:
pip install wikipedia-api
After installing the package, you can use the provided Python code without any issues.
ModuleNotFoundError: No module named 'pdfkit'
It seems that the pdfkit
module is not installed in your Python environment. This module is used to convert HTML files or strings to PDF.
You can install it using pip:
pip install pdfkit
After installing the package, you can use the provided Python code without any issues.
raise AssertionError( AssertionError: Please, be nice to Wikipedia and specify user agent - https://meta.wikimedia.org/wiki/User-Agent_policy. Current user_agent: 'en' is not sufficient.
The error message is indicating that you need to specify a user agent when making requests to the Wikipedia API. This is a requirement of the Wikipedia User-Agent policy.
The wikipediaapi
library allows you to specify a user agent when creating a Wikipedia object. Here's how you can modify the function to include a user agent:
import wikipediaapi import pdfkit def wiki_to_pdf(subject): wiki_wiki = wikipediaapi.Wikipedia('en', user_agent='MyProjectName/1.0 (http://example.com/my_project; my_email@example.com)') page_py = wiki_wiki.page(subject) if page_py.exists(): content = page_py.text pdfkit.from_string(content, f'{subject}.pdf') print(f'PDF saved as {subject}.pdf') else: print(f'No Wikipedia page found for "{subject}"') # Usage wiki_to_pdf('Python (programming language)')
In this updated code, I've added a user agent to the Wikipedia
constructor. You should replace 'MyProjectName/1.0 (http://example.com/my_project; my_email@example.com)'
with a user agent that accurately represents your project.
TypeError: Wikipedia.__init__() got multiple values for argument 'user_agent'
I apologize for the mistake. It seems that I made an error when specifying the user agent in the Wikipedia
constructor. The user agent should be specified as a keyword argument, not a positional argument.
Here's the corrected code:
import wikipediaapi import pdfkit def wiki_to_pdf(subject): wiki_wiki = wikipediaapi.Wikipedia(language='en', user_agent='MyProjectName/1.0 (http://example.com/my_project; my_email@example.com)') page_py = wiki_wiki.page(subject) if page_py.exists(): content = page_py.text pdfkit.from_string(content, f'{subject}.pdf') print(f'PDF saved as {subject}.pdf') else: print(f'No Wikipedia page found for "{subject}"') # Usage wiki_to_pdf('Python (programming language)')
In this updated code, I've specified the user agent as a keyword argument in the Wikipedia
constructor.
OSError: No wkhtmltopdf executable found: "b''" If this file exists please check that this process can read it or you can pass path to it manually in method call, check README. Otherwise please install wkhtmltopdf - https://github.com/JazzCore/python-pdfkit/wiki/Installing-wkhtmltopdf
The error message is indicating that the pdfkit
library can't find the wkhtmltopdf
executable, which is a tool used to convert HTML to PDF.
To resolve this issue, you need to install wkhtmltopdf
on your system. The installation process varies depending on your operating system.
Here are the installation instructions for some common operating systems:
Windows: Download the installer from the official website: https://wkhtmltopdf.org/downloads.html
macOS: You can install wkhtmltopdf
using Homebrew:
brew install wkhtmltopdf
Ubuntu/Debian:
sudo apt-get install wkhtmltopdf
CentOS/Fedora:
sudo yum install wkhtmltopdf
After installing wkhtmltopdf
, you should be able to use the provided Python code without any issues.
well done, the code and the debug instructions were all correct
