Adding a Python Source

Add a Python source 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 Integrations panel

2. Click Code (If you already have one or more sources integrated to the page, just click "+ Add")

1. 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.

Python Editor Features

CalcTree’s built-in Python editor includes:

• Syntax highlighting

• Autocomplete and inline hints

• Real-time error reporting

• Keyboard shortcuts

• Find and replace

This editor is powered by Monaco Editor, the same technology used in Visual Studio Code.
