BankClassify: simple automatic classification of bank statement entries

This is another entry in my ‘Previously Unpublicised Code’ series – explanations of code that has been sitting on my Github profile for ages, but has never been discussed publicly before. This time, I’m going to talk about BankClassify a tool for classifying transactions on bank statements into categories like Supermarket, Eating Out and Mortgage automatically. It is an […]

Blogroll

I really enjoy reading blogs. That seems to be a slightly outdated view, as many people have moved over to using Twitter exclusively, but I like being able to follow everything that a specific person writes, and seeing mostly long-form articles rather than off-the-cuff comments. Back in the day, when blogs were really popular, every […]

Regression in Python using R-style formula – it’s easy!

I remember experimenting with doing regressions in Python using R-style formulae a long time ago, and I remember it being a bit complicated. Luckily it’s become really easy now – and I’ll show you just how easy. Before running this you will need to install the pandas, statsmodels and patsy packages. If you’re using conda […]

Reminder about cross-platform case-sensitivity differences

This is just a very brief reminder about something you might run into when you’re trying to get your code to work on multiple platforms – in this case, OS X, Linux and Windows. Basically: file names/paths are case-sensitive on Linux, but not on OS X or Windows. Therefore, you could have some Python code […]

Showing code changes when teaching

A key – but challenging – part of learning to program is moving from writing technically-correct code “that works” to writing high-quality code that is sensibly decomposed into functions, generically-applicable and generally “good”. Indeed, you could say that this is exactly what Software Carpentry is about – taking you from someone bodging together a few […]

Resources for learning Python for Remote Sensing – or switching from IDL

I’m supervising an MSc student for her thesis this summer, and the work she’s doing with me is going to involve a fair amount of programming, in the context of remote sensing & GIS processing. She’s got experience programming in IDL from a programming course during the taught part of her Masters, but has no […]

How to: rescue lost code from a Jupyter/IPython notebook

Jupyter (formerly known as IPython) notebooks are great – but have you ever accidentally deleted a cell that contained a really important function that you want to keep? Well, this post might help you get it back. So, imagine you have a notebook with the following code: and then you accidentally delete the top cell, with […]
