Execute a python file in a Raspberry Pi 3 Xojo Desktop App

I will appreciate if someone could share the lines of code to execute a python file in a Raspberry Pi 3 XOJO Desktop App.
I tried with Shell command but with no success.

Should be easy. What command did you execute in the shell?
You probably need the full path to python for it to work.

/usr/bin/python path_to_script.py
(I don’t know if it IS in /usr/bin/ you need to check that.)

Take a look on this example from my pi with shell and python.

Is for read temperature from python script …

Thank you both.
It is done…
The comands where:
Dim s as new Shell
s.Execute (“python /home/pi/myfile.py” )
Very easy.
