Installation

Choose one of these options:

  1. Install via ComfyUI-Manager (search for "Execute Python")
  2. Use Custom Nodes Manager > Install via Git URL in ComfyUI-Manager
  3. Clone the repository into custom_nodes/ manually and install dependency from requirements.txt (or download .zip from GitHub and unpack it to custom_nodes/)

Usage

Write your Python code in the widget (it may include imports, functions and any other language features) and assign result variable somewhere in the code. If you use multiple outputs, use a tuple (for example result = 1, 2, 3).

[!IMPORTANT] For safety reasons, this node can't be used from shared workflows, which means that it would only work if you created it yourself.

[!WARNING] The code is executed with a simple exec, so execute only trusted Python code
