Adding flush to Python

[S0d4Dev]

I have worked in a simple mastermind game made in python, and made the following code to make the letters of the text appear with a delay between them (without making newlines).

import time
def message(message, delay) :
    for letter in message :
        print(letter, flush=True)
        time.sleep(delay)

Unfortunately, this doesn't seem to work on the calculator, and results in a TypeError:

Another way of doing this is using escape codes, such as \b for a backspace. This does work but gives a unwanted output :

To implement this flush feature, a first option would be to add the flush type, but that may not work if that is a limitation from Micropython itself. Another way to put it would be to add the sys module (or a part of it, such as stdout, if it can't fit in the calculator). The last option (that I can think of) would be to make the the escape codes such as \b work, but again, I don't know if there are some limitations around.
