[Maya-Python] Getting the name of the blendParent name of parentContraint

[yann19]

Hello all, I am doing some scripting for animation related and would like
some advice.


1. What is the best way that I can script such that if an object that has 2
static keyframes (same values keyed in those 2 frames), remove all
keyframes (akin to `break connections`)? I am doing it by iterating all the
attributes, then its values and storing them in a list. Followed by
comparing 2 lists, each list contains all the keyable values from each
frame... Is this the best way?

2. When doing a `parentConstraint`, the attribute - `blendParent` is always
created. However is there a command that allows me to grab the blendParent
name as soon as the constraint is done?
Currently in my code, it is hard-coded to find `blendParent1` but there are
times where `blendParent3` is created instead.
