            time.sleep(2)

        print('okayy')
    window=Tk()
    #button for stats
    btn=Button(window, text="click me for cpu stats", fg='blue')
    btn.place(x=80, y=100)
    btn.bind('<Button>',eventc)
    #btn for closing the window
    winclose=Button(window, text="close window", fg='blue')
    winclose.place(x=95, y=0)
    winclose.bind('<Button>',closewin)
    #for window
    window.title('my \'so called first app\'')
    window.geometry("300x200 10 10")
    window.mainloop()

When I click get cpu stats is gives me stats but the window will not respond after that. and after forcefully ending the window it give me this exit code:Process finished with exit code -805306369 (0xCFFFFFFF) can you help me why

CodePudding user response：

The while loop inside eventc() will block tkinter mainloop from handling pending events and updates. Suggest to use .after() to replace the while loop:

def eventc(event=None):
    print(psutil.cpu_stats())
    window.after(2000, eventc) # execute eventc() 2000ms later
