Trying to execute a python script from a shell and keep ending up with errors:  
Exception NilObjectException  
self MyWindow.MyWindow  
shell1 Nil

`Dim shell1 As Shell
'shell1.Execute("python /home/pi/Desktop/Upload.py aa bb cc")
`  
The aa bb and cc are separated with a space and are the three variables I am trying to pass to the python script.  
I have captured the command in a msgBox and pasted to the Terminal and it runs fine so there is something in the format of the shell that isn’t working. The python script is very basic and it works.  
Pasting the results of this message box into the Terminal works:

```auto
msgBox("python /home/pi/Desktop/Upload.py aa bb cc")
```

I have messed around with "\ " in the spaces from this thread but with no success.

Any help would again be appreciated.

Beatrix is correct, but you will also probably need an absolute path for python in your command. Shell is not initialized with the same PATH as a terminal environment would be.

_forehead slap_ Thank you Beatrix, can’t believe I missed that. That removed the error.  
Thank you Greg, I added an absolute path to python and now the script works as intended.

`Dim shell1 As New Shell
shell1.Execute("/usr/bin/python2.7 /home/pi/Desktop/Upload.py aa bb cc")`
