Dear all,

Is it possible for a Python script to detect whether it is running
interactively? It can be useful for e.g. defining functions that are
only useful in interactive mode.


Try the isatty() method (*) on e.g. stdin:

$ python -c "import sys; print sys.stdin.isatty()"
True
$ echo "" | python -c "import sys; print sys.stdin.isatty()"
False

Your test determines whether input is redirected. But I think the OP was asking how to detect whether the script was being run from an interpreter prompt.

That was my question indeed. Is it possible?
