Read and Write separately in python

Question

I'm trying to create a very simple program in python that needs to read input from the user and write output accordingly. I need an output similar to this:

$./program.py
say something: Hello World
result: hello world

The thing is that i need to read input indefinitely, each time the user inputs data i would like that the printed data doesn't obstruct the input prompt. It will even better that no newlines be printed, keeping the output as above: a line for reading and another for writing.

I tried using curses but i don't want the hole screen to be used, just the two lines.

I believe this is what you want:

import colorama
colorama.init()
no = 0
while True:
    user_input = str(raw_input('\033[2A'*no + '\033[KSay something: '))
    print '\033[KResult: ' + user_input
    no = 1

This how it looks after entering the string:

This implementation works on windows, however, if you use Linux, if I am not mistaken these are not necessary:

import colorama
colorama.init() 

EDIT: Modified my code a bit so it does not overwrite the text that was printed before the execution of the code. Also added an image of working implementation.

You can do veeeery simple trick:

from os import system
while True:
    system('clear')  # or 'cls' if you are running windows
    user_input = input('say something:')
    print('result: ' + user_input)
    input()
