Python tkinter module text transitioning

I just started Python a few days ago, and I have gotten to animations. I am working on one called "Bounce!", and it has that name on the screen, with other settings. The settings are FPS and Speed (increment). But, as an oval bounces, these settings change, and I want the text to change along with it, but I do not know how. This is my current code:

import time
from tkinter import *
tk = Tk()
fps=30
increment=2
canvas = Canvas(tk,height='500',width='500')
canvas.pack()
canvas.create_oval(175,100,325,250,fill='red',outline='black')
canvas.create_line(50,100,450,100)
canvas.create_line(50,450,450,450)
canvas.create_text(250,30,text='Bounce!',fill='red',font=('Consolas',30))
x = canvas.create_text(250,75,text=('FPS: %s; Speed: %s'% (fps,increment)),fill='black',font=('Consolas',20)) #mainproblem

while True:
    increment += 1
    if increment % 2 == 0 and fps > 1:
        fps = fps - 1
    #I want the 'x' text to change to the current FPS and Speed here, but I do not know how.
    for x in range(0, int(200/increment)):
        canvas.move(1,0,increment)
        tk.update()
        time.sleep(1/fps)
    for x in range(0, int(200/increment)):
        canvas.move(1,0,-(increment))
        tk.update()
        time.sleep(1/fps)

I am using Python 3.4.2.

import time
from tkinter import *
tk = Tk()
fps=30
increment=2
t = ('FPS: %s; Speed: %s'% (fps,increment))
canvas = Canvas(tk,height='500',width='500')
canvas.pack()
canvas.create_oval(175,100,325,250,fill='red',outline='black')
canvas.create_line(50,100,450,100)
canvas.create_line(50,450,450,450)
canvas.create_text(250,30,text='Bounce!',fill='red',font=('Consolas',30))
w = canvas.create_text(250,75,text= t,fill='black',font=('Consolas',20)) #mainproblem

while True:
    increment += 1
    if increment % 2 == 0 and fps > 1:
        fps = fps - 1
    t = ('FPS: %s; Speed: %s'% (fps,increment))

    canvas.itemconfig(w, text= t)

    for x in range(0, int(200/increment)):
        canvas.move(1,0,increment)
        tk.update()
        time.sleep(1/fps)
    for x in range(0, int(200/increment)):
        canvas.move(1,0,-(increment))
        tk.update()
        time.sleep(1/fps)

You can use itemconfigure to change the settings of elements on the canvas (see here). Also note that your loop variable x is shadowing the variable you assigned the ID of the text to.

text = canvas.create_text(...)
    ...
    canvas.itemconfigure(text, text=('FPS: %s; Speed: %s'% (fps,increment)))
