Bots perform many important tasks on Wikipedia such as adding categories and templates to thousands of articles to help maintain the site. There are over 1,000 approved bot tasks and 600 active bots currently running on the English Wikipedia alone. Only trusted users are allowed to create and run bots, which must be approved through a request process to ensure they are helpful and harmless. The Python Wikipediabot Framework provides tools for automating work on Wikipedia and other wiki sites using bots programmed in Python.
