Running a Python Script

[ToeKneeWhoWin]

I'm attempting to run a python script using the system exec.vi.  The python script calls for py files located in the folder where the script is located. An example is shown below.

When using the system exec.vi the labview program doesn't recognize the other py in the folder. Is there a way in the labview program to alleviate this issue?

Set the Working directory input. (or even better, use the Python node)
