at principle, it would be this:
cmds.sphere(n='sphere1')
cmds.sphere(n='sphere3')
if cmds.objExists('sphere2'):
cmds.select('sphere2')
print("exist")
else:
print("not exist")
//Result is not exist
But, if I use that other function:
cmds.joint (n='jts1')
cmds.delete( cmds.parentConstraint("sphere2","jts1"))
# TypeError: Object sphere2 is invalid #
