DisCoPy is a Python toolkit for computing with string diagrams.

• Documentation: https://docs.discopy.org
• Repository: https://github.com/discopy/discopy

Why?

Applied category theory is information plumbing. It’s boring… but plumbers save more lives than doctors.

As string diagrams become as ubiquitous as matrices, they need their own fundamental package: DisCoPy.

How?

DisCoPy began as an implementation of:

• DisCoCat (distributional compositional categorical) models,
• and QNLP (quantum natural language processing).

This application has now been packaged into its own library, lambeq.
