  1- try to run the last version of python, there is speed improvement in 3.10 and 3.11

       >>> import sys; sys.version
       '3.10.4 (main, Dec  2 2022, 17:52:13) [Clang 14.0.0 (clang-1400.0.29.202)]'
  
       51.94417405128479
       37.79175686836243
       100.8145821094513
  

  2- global variable lookup is costly in python, putting the whole thing in a main() function halves the running time

       22.97948908805847
       22.47922682762146
       59.1025867462158
