How can I make the circle move further after pressing the space bar?

Question

Python

from tkinter import*
def DrawCircle(x,y,r):
    h.create_oval(x-r,y-r,x+r,y+r,fill='black')

def right(event):
    h.move(1,5,0)
def left(event):
    h.move(1,-5,0)
def up(event):
    h.move(1,0,-5)
def down(event):
    h.move(1,0,5)
def space(event):
    h.delete('all')
    h['bg']='purple'
    h.create_oval(x-r,y-r,x+r,y+r,fill='black')
    
root=Tk()

root.bind('<Right>',right)
root.bind('<Left>',left)
root.bind('<Up>',up)
root.bind('<Down>',down)
root.bind('<space>',space)

h=Canvas(root,width=500,height=500,bg='purple')
x=250 
y=250
r=50
DrawCircle(x,y,r)
h.pack()
root.mainloop()

I can move the ball but after a space it stops responding to pressing the arrows. Help me please. on the arrows, it should move 5 pixels in the indicated direction. when you press the space bar, the ball should return to the starting point.

Answer 1

If my eyes do not fail me at 4 o'clock in the morning, then when I press the spacebar, another circle is created and it no longer has anything to do with events. Here you need to do this:

1. Create one single circle object (write to a variable for example)
   
2. Create variables with window center coordinates
   
3. When you press the spacebar, change the circle coordinate values ​​to the window center coordinate values
