When running gtts code, some lines (written before gtts code ) run after audio is played. I want some lines of code to run before audio is played

def play(audio):
    sound = gTTS(audio)
    sound.save('sound.mp3')
    playsound('sound.mp3')

def isCorrect(self, n):  # checking whether option clicked is correct or not and updating info
    if n == self.anspos:
        self.score = self.score + 1  # increasing score if correct
    self.progress = self.progress + 1  # increasing progress
    p.update()
    if self.progress != 10:
        p.newQues()  # going for next question if 10 questions are not yet completed
    else:
        Prog.grid_forget(), Score.grid_forget(), Q.grid_forget()  # removing unwanted labels and button
        A.grid_forget(), B.grid_forget(), C.grid_forget(), D.grid_forget()
        Result.grid(row="0", columnspan="2", pady="6", padx="10")  # adding result label
        final.set(("Congratulations!!,", "Your", "Score", "is", self.score, "/", "10"))  # setting result in gui.
        Quit.grid(row="1", column="1", padx="6", pady="10"), Restart.grid(row="1", column="0", padx="6", pady="10")
        play(str(("Congratulations, Your Score is", self.score, "out of 10.")))

Here all the GUI part is in else statement and that is executing after audio is played.

Just add window.update() before playing audio. window is tkinter.Tk()
