Each time I want to view a long output line, I have to drag the horizontal scroll bar. Is it possible to set word wrapping in PyDev's interactive console (not editor)?
Unfortunately no, it's not currently possible to enable word wrapping in the PyDev interactive console.
You may report this as a feature request in https://www.brainwy.com/tracker/PyDev (but even better would be providing a pull request for that -- see: http://www.pydev.org/developers.html)
