I have been looking for a way to do this for a long time (mark_seam (True\False) and mark_sharp (True\False)) with one button in my pie menu. I managed to achieve some kind of result. I found how to do one button bevel and crease.

How to determine if the seam is on only selected edges?

import bpy
import bmesh

obj = bpy.context.object
me = obj.data
bm = bmesh.from_edit_mesh(me) 
bw = bm.edges.layers.bevel_weight.verify()
cr = bm.edges.layers.crease.verify()
#se = bm.edges.layers.seam.verify()           ???
selected = [e for e in bm.edges if e.select]

if any(e[bw] == True for e in selected):




bmesh.update_edit_mesh(me, True)
