Adding a Python Node

Add a Python node to your page to create custom, script-based calculations using CalcTree’s built-in code editor.

Getting Started

To add a Python source:

1. Open the right-hand panel

2. Click in the Nodes tab

3. Click + and select Python

4. Start coding (A new code editor will appear at the bottom of your page with some initial helpful tips)

All code runs automatically once it is complete and has no errors.
