I seem to recall you making a thread about this before, and it was determined that printing the return values to stderr was a feature Python does in interactive mode.
As for it returning 15? It's actually very standard to give exit() a code in most languages, if Python didn't it'd be the weird one. And it is documented,
here:
Quote:
The optional argument arg can be an integer giving the exit status (defaulting to zero), or another type of object. If it is an integer, zero is considered “successful termination” and any nonzero value is considered “abnormal termination” by shells and the like. Most systems require it to be in the range 0–127, and produce undefined results otherwise.
Yes, the exit value is communicated to BASH, the calling process, that is its function, to tell it whether the program succeeded or failed.
