# Tool Use

For most real-world applications, language models will have to access information by controlling tools—doing web searches, checking your calendar, looking up emails, or running calculations. We’ll look at two examples here:

1. [Running web searches using Google](/chapters/tool-use/web-search.md)
2. [Executing computations using the Python interpreter](/chapters/tool-use/interpreters.md)

In both cases, we’ll extend [the basic question-answerer](/chapters/question-answering/q-and-a-about-short-texts.md).
