How to create Pyspark code that will create a white space in Databricks Notebook cell


I would like help with Python(PySpark) that will continually create a white space or simply move the cursor in a Databricks notebook cell.

For example, in the image I have manually moved the cursor across, is there a way I can write code to automate the moving of the cursor in the notebook cell.

enter image description here


Solution

  • To the best of my knowledge, Python code does not have native access to the cursor position within a notebook cell in a Databricks notebook, as that is typically managed by the notebook's frontend interface (such as the JavaScript running in the web browser). Therefore, it is not possible to directly control cursor movement within a Databricks notebook cell using Python or PySpark code alone.

    However, there are alternative approaches if the goal is to create activity or simulate "keep-alive" behavior within the notebook. you can use time.sleep() in a loop to keep a cell-active.

    import time
    
    # Keep cell active for a specific period
    for I in range(3600*2):                  # 2 hours but you can adjust the range as needed for longer or shorter activity
        print(f"Iteration {i+1}", end="\r")  # This will update the line repeatedly
        time.sleep(1)                        # Sleep for 1 second, adjust as needed
    

    You might also consider adjusting the cluster timeout settings or using Databricks REST API to programmatically check and restart clusters if needed.
