I tried to get (every frame) the Weight with the following script, but it didn't work I tried to get the Weight by using the following script, but I could not get the Weight change by Dynamic Paint.

### Python Code
import bpy
meshName: str = 'Cube'

vars


obj = bpy.data.objects[meshName]


def handler(Scene):


# count vertices
weight = [0]*len(obj.data.vertices)

# get and assign weight 
for i in range(len(obj.data.vertices)):
    try: weight[i] = obj.vertex_groups[0].weight(i)
    except: pass
print(weight)




bpy.app.handlers.frame_change_pre.append(handler)

The weight obtained by vertex_groups can only be obtained before Dynamic Paint is applied. Also, I could not get the value by duplicating the vertex group in the modifier and referencing it.

How can I fix this?
