ipython notebook clear cell output in code
In a iPython notebook, I have a while loop that listens to a Serial port and
What I want to achieve to only show the latest received data (i.e only one line showing the most recent data. no scrolling in the cell output area)
What I need(i think) is to clear the old cell output when I receives new data, and then prints the new data. I am wondering how can I clear old data programmatically ?
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() print("Hello World!")
At the end of this loop you will only see one
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.
