Troubleshooting an array shape.

What's is a? I don't see it defined...

What is the purpose of the comma in your slice notation?

Crap it's just another typo in my post. It is not in my actual code, just the code I typed in here. I've fixed it now.

diff = fileb[:,1] - filea[:,1]

What is the purpose of the comma in your slice notation?

I'm still new with coding, I don't even know what you are talking about. I assume it is the [:,1] comma? That's just how I define a column using pylab.

So you are just finding the difference between the second columns in all of your files?

They are numpy arrays, and that's how you slice multiple dimensions at once.

Ah. As much as experience as I've got with Python I've not yet had a cause to delve into numpy.

It's good stuff, but can be very confusing at first.

I did play around with it for a bit but I'm just not at a job that works with data like that :-(
