ipython notebook clear cell output in code

Question

In a iPython notebook, I have a while loop that listens to a Serial port and print the received data in real time.

What I want to achieve to only show t

Answer 1

You can use IPython.display.clear_output to clear the output of a cell.

from IPython.display import clear_output

for i in range(10):
    clear_output(wait=True)
    print("Hello World!")

At the end of this loop you will only see one Hello World!.

Without a code example it's not easy to give you working code. Probably buffering the latest n events is a good strategy. Whenever the buffer changes you can clear the cell's output and print the buffer again.
