# Native Symbol
|
|
|
|
This sample demonstrates how to declare a Python function as `NativeSymbol`.
|
|
|
|
Steps of the example:
|
|
1. Load WASM from Python
|
|
2. Call `c_func` from WASM.
|
|
3. `c_func` calls `python_func` from Python.
|
|
4. `python_func` calls `add` from WASM.
|
|
5. Result shown by Python.
|
|
|
|
## Build
|
|
|
|
Follow instructions [build wamr Python package](../../README.md).
|
|
|
|
Compile WASM app example,
|
|
|
|
```sh
|
|
./compile.sh
|
|
```
|
|
|
|
## Run sample
|
|
|
|
```sh
|
|
python main.py
|
|
```
|
|
|
|
Output:
|
|
|
|
```
|
|
python: calling c_func(10)
|
|
c: in c_func with input: 10
|
|
c: calling python_func(11)
|
|
python: in python_func with input: 11
|
|
python: calling add(11, 1000)
|
|
python: result from add: 1011
|
|
c: result from python_func: 1012
|
|
c: returning 1013
|
|
python: result from c_func: 1013
