How can I change the transform by minimal code? I'm a beginner and I just want to set the location, rotation, and scale of the object.
I tried to get code by reverse engineering but when I moved, rotated, and scaled my object I saw complicated code.
if you want to get exact code you shouldn't change transform in view port.
when you change the transform in this panel it works:


Location
import bpy

obj = bpy.context.object
obj.location = (0,0,0)

Rotation
import bpy
import math

obj = bpy.context.object
obj.rotation_euler = (0,math.radians(90),0)

Scale
import bpy

obj= bpy.context.object
obj.scale = (1,1,1)
