I am looking to seasonally adjust monthly data, using Python. As you can see from these series: http://www.emconfidential.com, there is a high seasonal component to the data. I would like to adjust for this so that I can better guage if the series trend is rising or falling. Anybody know how to do this easily using scipy or other Python library?

There’s no magical python library that will do seasonal adjustments for you. Applications that do this kind of thing tend to be rather large.
You’ll need to work out the maths yourself and then use scipy to calculate the rest for you.
