Why I've got an AttributeError

[XiuhengWu]

I used Python 3.10.12 to run buffon.py, and receiving the following Error:

Traceback (most recent call last):
  File "D:\Personal_files\User_document\Downloads\buffon.py", line 134, in <module>
    main()
  File "D:\Personal_files\User_document\Downloads\buffon.py", line 131, in main
    bsim = Buffon_Sim()
  File "D:\Personal_files\User_document\Downloads\buffon.py", line 66, in __init__
    fig.canvas.set_window_title(window) #window title
