Trying to use a canvas oval item as a status indicator

HomeCategory: stackoverflowTrying to use a canvas oval item as a status indicator

I am trying to color the canvas oval item, indicating when the program is busy (status indicator). The expected behavior is to turn the canvas oval red when clicking the check button, and turn it back off (to blue ) when the function is complete.

Here is the code I have so far

class App(tk.Tk):
    def __init__(self):  
        self.entryframe = Frame(self, width=800, height=500)
        self.entryframe.pack(fill=X, padx=8, pady=8)
        self.canvas = Canvas(self.entryframe, width=30, height=30)
        # change fill color of the status oval
        self.status = self.canvas.create_oval(10, 10, 30, 30, fill="blue", tags="state")
        self.canvas.grid(row=0, column=1)
        self.label = Label(self.entryframe, text="Enter your sentence:").grid(row=3, column=0, sticky=W)
        self.text = Text(self.entryframe, wrap=WORD, width=70, height=10)
        self.text.grid(row=4, column=0, sticky=W)
        self.btn_h = Button(self.entryframe, text="Check", width="15", command=self.check_input).grid(row=5, column=0, padx=8, pady=8)

    def check_input(self):
        #change status oval color to red
        self.canvas.itemconfig(status, fill='red')

        # after the function is complete turn it back off
        canvas.itemconfig(light_1, fill='blue')

root = App()

The current behavior is the item stays blue color, and does not change at all.
