Result
Returns result or error.
Description
Runs a Python script.Pass the script text to run. Returns the result of the script.
Before running a specific script, you may run a prefix script to setup sys.argv with the arguments you like to have. Python.SetValue can help to set a few global variables.
The script runs within the FileMaker process. If you cause an endless loop, FileMaker freezes and needs to be force quit, so please always include an exit condition for your loops. Also if you get Python to crash, FileMaker will crash with it. Use Shell functions to run Python in a separate process.
You may want to use Process.SetCurrentDirectory function to set the current directory, so local files are found.
Examples
Try it:
Set Variable [ $r ; Value: MBS("Python.Run"; $p; "x = 1¶if x == 1:¶ # indented four spaces¶ print('x is 1.')") ]
Set Variable [ $o ; Value: MBS("Python.PrintOutput"; $p) ]
If [ MBS("IsError") or $o ≠ "x is 1.¶" ]
Show Custom Dialog [ "Failed to evaluate" ; $r ]
Exit Script [ Text Result: ]
End If
Set Variable [ $o ; Value: MBS("Python.PrintOutput"; $p) ]
If [ MBS("IsError") or $o ≠ "x is 1.¶" ]
