Crossing the Bridge

To use a Python library, your Mojo values must cross into Python first. That hand-off is the heart of interop. 🌉

Numbers Convert

Mojo numbers turn into Python numbers automatically when you pass them. A Mojo Int becomes a Python int the library can read.

var n = 42
var result = np.array([n])

Build Python Lists

Many NumPy calls expect a Python list. You can write the list literal right inside the call, and Mojo passes it across the bridge.

var a = np.array([1, 2, 3, 4])

The PythonObject Type

On the Python side, everything is a PythonObject. It is Mojo's wrapper for any value living in the Python world.

var obj: PythonObject = 3.14

Wrap a Value

Annotate a value as PythonObject to convert it for Python. Mojo handles turning your number into the matching Python type.

var py_x: PythonObject = 10

Strings Cross Too

Mojo strings convert into Python strings the same way, so you can pass text labels and names straight into Python functions.

var name: PythonObject = "mojo"

Pass as Arguments

Once converted, just hand values to a Python call as arguments. The library receives normal Python objects and works as usual.

var scaled = np.multiply(a, 2)

Mark It raises

Conversions and Python calls can fail, so wrap this work in a function marked raises to stay safe.

fn send() raises:
    var py_x: PythonObject = 5

Mind the Copy

Crossing the bridge often copies data into Python's memory. That copy has a cost, so pass big buffers thoughtfully.

Lists of Numbers

You can also pass a Mojo list of values into Python. Each element converts as it crosses, arriving as a Python list.

var data = [1.0, 2.0, 3.0]
var arr = np.array(data)

Why It Matters

Smooth conversion means your Mojo numbers and text flow into any Python library, letting you reuse powerful tools without friction. ✨

Quick Check

Recall the type that represents a value once it lives on the Python side.

Recap

You saw Mojo numbers and strings convert into PythonObject values, ready to pass as arguments into any Python call across the bridge. 🎯
