Python3Script Xojo Plugin

Python3Script.PythonIsFound Method

Checks if valid Python installation is found. Optionally a constant can also be passed in to hint which version of Python is preferred if Python has not already been loaded.

shared PythonIsFound(
   preferredVersion as Python3Script.PreferredVersionValues) as Boolean

Parameters

preferredVersion
Optional parameter: With this parameter you can pass in Python3Script.PreferredVersionValues enum value to hint which Python version you prefer if more than one is found.

Returns

Boolean
True if valid Python 3.4.x, 3.5.x, 3.6.x, 3.7.x or 3.8.x installation was found, else false.

Remarks

Version 3.4.x, 3.5.x, 3.6.x, 3.7.x or 3.8.x is needed for this plugin. If you want for 2.7.x then please check our other PythonScript plugin.

Its good practice to for example put check like this in your Application.Open event, like for example:

Sub Open()
    If not Python3Script.PythonIsFound() then
       MsgBox "Correct Python installation was not found on this machine"
       Quit()
    else
       Python3Script.Init("TestApp")
    end if
End Sub


And then your close event would look like this:

Sub Close()
    If Python3Script.PythonIsFound() then
       Python3Script.Finalize()
    end if
End Sub
