Python Example

This example demonstrates building and running a simple WASM component in Python using Tarawasm.

Steps

1. Initialize Extract WIT definitions and save project config:

   tarawasm init --lang python --wasm-file docs:adder@0.1.0.wasm adder

2. Generate bindings

   tarawasm bind

3. Write your code Create main.py in the project root:

   from adder import exports
   
   class Run(exports.Run):
       def run(self) -> None:
           print("Hello from Python WASM!")

4. Build

   tarawasm build

   This produces adder.wasm in the current directory.

5. Run Use any WASM runtime, e.g. Wasmtime:

   wasmtime adder.wasm
   # Output:
   Hello from Python WASM!
