Set EasyOut on a keyframe with python

[maurizio1974]

Hello

I am trying to set the correct slope and accelleration on two keyframe so that I can get an easy put on the first keyframe.
I know that there is the setSlope and setAccell method for a hou.keyframe , but those value change depending on the 
distance and the values of the respective keyframes.
I know in the animation editor there is the button that calculates that and set it on both keyframes so tha thte curve 
properly goes from easyout to the second keyframe , but I don;t know what script or function that button runs.

Any help would be greatly apriciated
Cheers

Hello

Inc ase somebody else bump into this , I found a solution by setting hte keyframe as linear, then changing it to bezier and then set the slope to 0
that way houdini calculate the correct easy in/out of the curve

# Here I make the keyframe and set it to livear()
key= hou.Keyframe()
key.setExpression('linear()')
key.setValue(10)
parm.setKeyframe(key)

# Then re-set the keyframe again after changing hte function of the curve as bezier()
key.setExpression('bezier()')
key.setSlopeAuto('on')
key.setSlope(0)
key.setValue(10)
parm.setKeyframe(key)

Obviously you need two keyframes to make it work and than change the function of the curve
and this does the trick , for me at least
