arcpy let user automatically turn on the label, use label expression to save our time. is there a way how to change the position of the label like we use to do on label properties like screenshot below ?

so if i want to change the label placement/position of 100 layers, even i can use arcpy to turn on and use label expression using arcpy, i still have to double click into layer properties to change the label placement anyway?

i assumed there is away to solve that, any suggestion?

what i need to do is put the label in top of the point feature, but the default is on the top right of the feature.
