Get driver value from driven python maya

[maxime-picot]

Hello!

I would like to retrieve the driver values ​​for my driven keys but I cannot retrieve them.

For example, I have my object A driver with a custom attribute and object B driven
When :
A = 0
B = 2

A = 5
B = 10

A = -5
B = -3

I have this line which allows me to retrieve the values ​​of the driven:

cmds.keyframe(driven_attr, query=True, valueChange=True)

So I manage to have:
B = [2,10,-3]

but how to get the value of A when B = 2?

Is there something similar to get the driver values ​​corresponding to these values?

setDrivenKeyframes are not keys but floats.  So use the same query but change "valueChange" to "floatChange".
