Tkinter Generate/Delete Shapes with Keyboard Events

Here's a part - I'm having issues with what I commented out. I notice that this stops the terminal from continuing to read input, which I don't want at all. I want input to constantly get processed and not wait for one task to get done to move on, as the user will be pressing these keys frequently. I also am not sure how to simulate a keydown/keyup in here and would prefer that for getting the shape to appear/disappear rather than to use a regular timer for making the shape disappear.

import tkinter as tk

def enter_pressed(event):
	print("Key pressed: ENTER")
	box = c.create_rectangle(50, 50, 100, 100, fill="red")
	# root.after(3000, c.delete(box))

def space_pressed(event):
	print("Key pressed: SPACE")

def main():
	root.bind("<Return>", enter_pressed)
	root.bind("<space>", space_pressed)

	root.mainloop()

root = tk.Tk()
root.title("My app")
root.geometry('500x500')
c = tk.Canvas(root, height=500, width=500, bg="blue")
c.pack()

main()
