biochemistry - How do I get the current "camera position" in PyMol so I can reuse it in scripts?

I have a few protein models I want to take pictures of with various ligands bound. It would be nice if I could do it from the same "position", but the only way I can figure out to repeat the same view is with zoom resi. 64, 152, 150 or the like, which isn't framed that well.



How can I manually position the viewport, capture it's parameters, and repeat it in the script?




I have found get_view, e.g.



PyMOL>get_view
### cut below here and paste into script ###
set_view (
0.590180993, 0.670941532, 0.448923886,
-0.507570565, 0.740831316, -0.439937204,
-0.627747774, 0.031782545, 0.777776182,
0.000000000, 0.000000000, -417.497009277,
0.741809845, 7.078243256, 16.473480225,
329.157806396, 505.836212158, -20.000000000 )
### cut above here and paste into script ###


but this doesn't work in a .py script, where I need to modify it to cmd.set_view(...), as it complains it wants just (or up to 5) arguments, not 18. The wiki is vague about it, it just says




PYMOL API



cmd.set_view(string-or-sequence view)
