+--- Thread: How to Run a Cell in Jupyter Notebook Only If a Value Is Null? (/thread-how-to-run-a-cell-in-jupyter-notebook-only-if-a-value-is-null)

Hey! I’ve been using `nbclient` to programmatically execute cells in Jupyter notebooks. It’s part of the Jupyter ecosystem and works like a charm.
```python
from nbclient import NotebookClient
if some_value is None:
client = NotebookClient(nb)
client.execute()
```
This lets you control exactly which cells run based on conditions. Check out the [nbclient docs](https://nbclient.readthedocs.io/) for more info!

Yo, I feel like everyone’s overcomplicating this. Just use a simple `if-else` and suppress output with `;` at the end of the line.
```python
if some_value is None:
print("Value is null, doing stuff now!")
else:
pass;
```
This will skip the cell output if the value isn’t null. Sometimes the simplest solution is the best!
