SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Mojo developers often need to leverage Python libraries or expose Mojo types to Python. This skill provides a structured approach to cross-language interoperability between Mojo and Python, including data exchange, Python extension modules, and Python calls from Mojo.

Core Features & Use Cases

  • Mojo → Python: call Python libraries and functions from Mojo using PythonObject and Python import bindings.
  • Python → Mojo: convert Python objects to Mojo types and export Mojo types to Python via PythonModuleBuilder.
  • Extension modules: build Python extension modules that expose Mojo functionality to Python and embed Python into Mojo workflows.

Quick Start

Import a Python module from Mojo and evaluate a simple expression to verify Mojo–Python interop.

FAQPage Schema
How do I call Python libraries from Mojo?▼

You can call Python libraries from Mojo by using PythonObject and Python import bindings to bridge the Mojo and Python runtimes. This enables direct evaluation of Python functions and data exchange within Mojo workflows.

How do I expose Mojo types to Python?▼

You can expose Mojo types to Python by building Python extension modules via PythonModuleBuilder. This allows you to convert Python objects to Mojo types and export Mojo functionality for use in Python scripts.

Can I embed Python into a Mojo workflow?▼

Yes, you can embed Python into Mojo workflows by building Python extension modules that expose Mojo functionality. This requires a Python runtime to implement and load the cross-language components.

Do I need a Python runtime to use Mojo Python interop?▼

Yes, Mojo Python interop requires a Python runtime alongside the Mojo Python bindings to implement and load cross-language components. These bindings facilitate data exchange and function calls between the two languages.

What is the best way to build Python extension modules in Mojo?▼

The best way to build Python extension modules in Mojo is using PythonModuleBuilder to export Mojo types. This structured approach handles cross-language interoperability, enabling seamless data exchange and Python calls from Mojo.
