analog clock using tkinter on python but as soon as i run it it stops after 1 second

thats my code but as soon as i run it it stopped after 1 second

i tried making a clock but it stopped working after 1 second
keep in mind i am super super new and i would really appreciate any help since this is my project for 11th grade cs

i had issues with the code before this but i managed to figure them out and fix them on my own but i cannot seem to figure out how to fix this.
as soon as i run the code the tkinter window open and the second hand moves once but it stops and doesnt move again, i thought maybe the seconds hand had the problem but i waited a minute and the minute hand didnt move either so idk what to do now please help me out.

The issue with the provided code is that the function live_clock() is called only once after a delay of 1000 milliseconds using canvas.after(1000, live_clock). This is why the clock moves only once and then stops.

This might work:
