I would like to run a simple external Python file that prints “Hello World”, just as a test. I’ve tried researching running an external Python file, but I haven’t exactly found a straight answer yet. Any help would be appreciated.

Prerequisite

Python installed on the local system
test.py

Answer

Use Godot’s OS.execute()function which is similar in operation to Python’s Subprocess

var pystdout
OS.execute("python", ["path_to_test.py"], true, pystdout)
print(pystdout)

Need-to-know

Avoid calling this function on the main thread as inorder to get output, execution is blocked until python is finished

Reference

OS.Execute()

Thanks for the answer!

Not a problem.

Imagine having over the years amassed a huge library of libraries and operations in Python that isn’t simply transferable to GDscript or would take too much time to.

With the above in mind know that OS.execute() can also be ran in the Godot editor through plugins and tool scripts effectively operating full python programs in the process
