class App:
    def __init__(self, master):
        frame = Frame(master)
        frame.pack()
        # increment 步长
        s1 = Spinbox(frame, from_=0, to=100, increment=5)
        s1.grid(row=1, column=0, columnspan=2)

        def prints1():
            print("你选择的数字是", s1.get())
        Button(frame, text="打印数字", command=prints1).grid(row=2, column=0, columnspan=2)


root = Tk()
