## Ejemplo
|
|
|
|
```python
|
|
from notebook.jupyter_write import (
|
|
jupyter_append_code,
|
|
jupyter_append_markdown,
|
|
jupyter_insert_cell,
|
|
jupyter_edit_cell,
|
|
jupyter_delete_cell,
|
|
)
|
|
|
|
# Anadir celda de codigo al final
|
|
result = jupyter_append_code(
|
|
notebook_path="notebooks/01_analisis.ipynb",
|
|
source="import pandas as pd\ndf = pd.read_csv('data.csv')",
|
|
server_url="http://localhost:8888",
|
|
token="mi-token",
|
|
)
|
|
# {"action": "append_code", "cell_index": 5, "notebook": "notebooks/01_analisis.ipynb"}
|
|
|
|
# Anadir celda markdown
|
|
result = jupyter_append_markdown(
|
|
notebook_path="notebooks/01_analisis.ipynb",
|
|
source="## Resultados\n\nAnalisis de los datos obtenidos.",
|
|
)
|
|
# {"action": "append_markdown", "cell_index": 6, "notebook": "notebooks/01_analisis.ipynb"}
|
|
|
|
# Insertar celda en posicion 2
|
|
result = jupyter_insert_cell(
|
|
notebook_path="notebooks/01_analisis.ipynb",
|
|
cell_index=2,
|
|
source="# celda insertada",
|
|
cell_type="code",
|
|
)
|
|
# {"action": "insert", "cell_index": 2, "cell_type": "code", "notebook": "..."}
|
|
|
|
# Editar celda existente (indice 0)
|
|
result = jupyter_edit_cell(
|
|
notebook_path="notebooks/01_analisis.ipynb",
|
|
cell_index=0,
|
|
source="# Titulo actualizado",
|
|
)
|
|
# {"action": "edit", "cell_index": 0, "notebook": "..."}
|
|
|
|
# Eliminar celda
|
|
result = jupyter_delete_cell(
|
|
notebook_path="notebooks/01_analisis.ipynb",
|
|
cell_index=3,
|
|
)
|
|
# {"action": "delete", "cell_index": 3, "notebook": "..."}
|
|
```
|
|
|
|
## CLI
|
|
|
|
```bash
|
|
# Anadir celda de codigo
|
|
python -m notebook.jupyter_write append-code notebooks/01.ipynb "print('hola')" --server http://localhost:8888 --token mi-token
|
|
|
|
# Anadir celda markdown
|
|
python -m notebook.jupyter_write append-markdown notebooks/01.ipynb "## Titulo"
|
|
|
|
# Insertar en posicion 2
|
|
python -m notebook.jupyter_write insert notebooks/01.ipynb 2 "x = 42" --type code
|
|
|
|
# Editar celda 0
|
|
python -m notebook.jupyter_write edit notebooks/01.ipynb 0 "# Nuevo titulo"
|
|
|
|
# Eliminar celda 3
|
|
python -m notebook.jupyter_write delete notebooks/01.ipynb 3
|
|
```

## Notas
|
|
|
|
- Todas las funciones son sincronas publicamente. Internamente usan `asyncio.run()` sobre corutinas async que se comunican via WebSocket con `NbModelClient`.
|
|
- El `notebook_path` es relativo al servidor Jupyter (no al filesystem local).
|
|
- Si el servidor no esta corriendo o el token es incorrecto, lanza excepcion de conexion de `jupyter_nbmodel_client`.
|
|
- NO ejecuta celdas — solo modifica la estructura. Para ejecutar, usar el MCP de Jupyter o la API REST de Jupyter.
|
|
- `server_url` y `token` tienen defaults convenientes para desarrollo local (`http://localhost:8888`, token vacio).
|
|
- El campo `cell_index` en el resultado refleja la posicion final de la celda en el notebook.
