I know how to get all UV Loops using bmesh, get the mesh vertex and loop uv coordinates and index, select, translate, etc.:

for face in bm.faces:
    for loop in face.loops:
            l = loop[uv_layer]
            l.uv
            l.select =True
            loop.vert.index

I want to know all selected and connected edges

at this moment, only get all selected uv vertex index

selected = []


for face in bm.faces:
    
    for loop in face.loops:
        l = loop[uv_layer]
        if l.select:
            selected.append(loop.index)   
            print(selected)

enter image description here
