Tkinter Generate/Delete Shapes with Keyboard Events

[Larz60+]

Use a lambda statement, after needs to a function

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, lambda: 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()

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