How to Flush the Output of the Python Print Function
Do you want to build a compact visual progress indicator for your Python script using print(), but your output doesn’t show up when you’d expect it to? Or are you piping the logs of your script to another application, but you can’t manage to access them in real time?

- Determine when you need to flush the data buffer explicitly and when that
