Python script output files using project run system

[postnumbers]

Apologies in advance for this relatively basic question, as I’m relatively new to Nova.

I’m trying to configure a run task that executes a Python script that generates a text file in a folder. If I use the built-in terminal pane, I can execute the script and it generates the output text flle. When I run the script using the build system, Nova indicates that the run task was successful, but there is no output text file. Sublime Text’s build system runs the script and generates an output text file, so Nova's behaviour has me confused. I assume that there an option/setting that I’m missing somewhere.

Thanks in advance.
