There is no direct way to detect the interactive flag. However sys.ps1
and sys.ps2 are not set unless the interpreter runs in interactive mode.
isinteractive = hasattr(sys, "ps1")
The trick doesn't work if you want to get the flag's state before the
interactive interpreter starts.
You could query the internal state of the Py_InteractiveFlag flag with
ctypes. sys.flags does it, too.
