 Homebrew draws a distinction between Python **applications** and Python **libraries**. The difference is that users generally do not care that applications are written in Python; it is unusual that a user would expect to be able to `import foo` after installing an application. Examples of applications are [`ansible`](https://github.com/Homebrew/homebrew-core/blob/HEAD/Formula/a/ansible.rb) and [`jrnl`](https://github.com/Homebrew/homebrew-core/blob/HEAD/Formula/j/jrnl.rb).
 
-Python libraries exist to be imported by other Python modules; they are often dependencies of Python applications. They are usually no more than incidentally useful in a terminal. Examples of libraries are [`py2cairo`](https://github.com/Homebrew/homebrew-core/blob/HEAD/Formula/p/py2cairo.rb) and the bindings that are installed by [`protobuf`](https://github.com/Homebrew/homebrew-core/blob/HEAD/Formula/p/protobuf.rb).

An example of a library is the bindings that are installed by [`protobuf`](https://github.com/Homebrew/homebrew-core/blob/HEAD/Formula/p/protobuf.rb).
 
 Bindings are a special case of libraries that allow Python code to interact with a library or application implemented in another language.
