[Tkinter] Updating tkinter text

[BliepMonster]

It works also like this:

import tkinter as tk

import time

def get_time(canvas):
    show = time.strftime(f'%I:%M:%S %P')
    canvas.itemconfig(var, text=show)
    canvas.after(1000, get_time, canvas)

root = tk.Tk()

canvas = tk.Canvas(root, width=600, height=500, bg='antiquewhite')
show = time.strftime(f'%I:%M:%S %P')
var = canvas.create_text(300,100, text=show, fill='blue', font=('serif', 20, 'bold'))
canvas.pack()

get_time(canvas)

root.mainloop()

Greetings wuf

I tried running the code.

Error:
Traceback (most recent call last):
  File "C:\Users\Wannes\canvas update.py", line 13, in <module>
    show = time.strftime(f'%I:%M:%S %P')
ValueError: Invalid format string
