Hi After upgrading to Pythonista 3 I ended up with two apps on the ipad the old blue Py 2 and the new green Py 3. Shall I delete the Py 2 app and start all over with Py 3? BTW Some code I have been working on in Py 3 seems to have been lost.
Thank you MartinPacker in future I will try to format my posted code properly - actually it was a copy/paste situation from another source.
Thank you ccc I upgraded to Pythonista 3 and indeed the nice 3D vector plot appeared :)
