Question

I have a python script which receives values in real-time. My script prints the values as they are received and currently, each update is printed to the screen and the outpu

You can pass end='\r' to the print() function. '\r' represents a carriage return in Python. In Python 3 for example:

import time
for i in range(10):
    print('Update %d' % i, end='\r')
    time.sleep(5)

Here time.sleep(5) is just used to force a delay between prints. Otherwise, even though everything is being printed and then overwritten, it will happen so fast that you will only see the final value 'Update 9'. In your code, it sounds like there is a natural delay while some processes is running, using time.sleep() will not be necessary.
