How to change pointer location in python?

Question

I want to draw some special words while the program receives them, actually in real time. so I wrote this piece of code that does it well, but I still have a problem with changing the location of the pointer using the navigation keys on the keyboard and start typing from where I moved it. can anyone give me a hint how to do this? here is the CODE:

from colorama import init
from colorama import Fore
import sys
import msvcrt
special_words = ['test' , 'foo' , 'bar', 'Ham']
my_text = ''
init( autoreset = True)
while True:
    c = msvcrt.getch()
    if ord(c) == ord('\r'):  # newline, stop
        break
    elif ord(c) == ord('\b') :
        sys.stdout.write('\b')
        sys.stdout.write(' ')
        my_text = my_text[:-1]
        #CURSOR_UP_ONE = '\x1b[1A'
        #ERASE_LINE = '\x1b[2K'
        #print ERASE_LINE,
    elif ord(c) == 224 :
        set (-1, 1)
    else:
        my_text += c

    sys.stdout.write("\r")  # move to the line beginning
    for j, word in enumerate(my_text.split()):
        if word in special_words:
            sys.stdout.write(Fore.GREEN+ word)
        else:
            sys.stdout.write(Fore.RESET + word)
        if j != len(my_text.split())-1:
            sys.stdout.write(' ')
        else:
            for i in range(0, len(my_text) - my_text.rfind(word) - len(word)):
                sys.stdout.write(' ')
    sys.stdout.flush()
