  • How do I make a multi-line string in Python (so I can ctrl+C my SQL code)

    August 29th, 2023 in Blog, Jupyter, Machine Learning, Python, Spark, SQL

    This should be a quick one, but it is something that took me a little while to work out, but now I know I use it pretty much every day in my projects to save me a lot of time. This is the ability to copy and paste my SQL code into my python code as a multi-line string without having to reduce it to be all on one line or using escape characters.

  • Deploy Azure AutoML Model And Consume In Excel

    May 31st, 2022 in Blog, Machine Learning, Uncategorized

    It has come back to my turn to write a blog post, and if you remember my previous one concerned why you should use Azure based AutoMl and subsequently how to do so. If you followed that then you will be left with a model of which you’ve scored and know the performance of, but no way of how to then deploy and use your model. I will outline the steps needed to do this (which involves a major shortcut as we are using an AutoMl model), and…
