Just for my own understanding, could you explain why python is not an option
for your problem when you are calling out from it to mel commands?
What specifically requires that you do a mel.eval() from a python environment?
I must be missing something :-)
If "one liner" keyframe range setting is what you needed, here are some
interesting python one-liners:
Value is the same: (this is a 'duh' I'm sure, but just starting with it)
cmds.setKeyframe("polySphere2.sa", t=(1,5), v=18)
otherwise...
list comprehension:
_ = [cmds.setKeyframe("polySphere2.sa", t=k, v=v) for k,v in ktv = [(1,18),
(5,18)]]
mapping:
_ = map(lambda x: cmds.setKeyframe("polySphere2.sa", t=x[0], v=x[1]), ktv =
[(1,18), (5,18)])
