Итак, я создавал программу типа Personal Assistant на python, но в середине отладки она перестала открывать окно GUI. У меня есть root.mainloop, и в оболочке не отображаются ошибки. Есть предложения? Это один из моих первых проектов Tkinter, поэтому могут быть некоторые действительно очевидные вещи, которые я пропустил 🙂

root = Tk()
root.title = "PPA"


def Greet():
    #Generate a greeting
    greeting = choice(["Welcome back", "Hello", "Good to see you"])
    #Greet the user
    PPA.set(greeting,"Master")
    time.sleep(0.7)

def Main(need, user):
    global needed
    while needed == True:
        #Ask user what they need
        PPA.set("What would you like to do?")
        if need == "CODE":
            PPA.set("Ok, I will open up the code editor")
            path = "geany"
            subprocess.call(path)
        elif need == "INTERNET":
            PPA.set("Ok, I will open the internet browser")
            path = "chromium-browser"
            subprocess.call(path)
