As someone who made that choice a while back, I can understand your reasons. I was also familiar with Python from my projects at college and so Django was a natural choice for building a web app. But, I struggled with a lot of basics in Django and then switched to Rails. I can speak with confidence that Rails ecosystem is amazing and the learning curve is easier thanks to the bunch of tutorials and screencasts available.

Though, I hear that the beginner resources in Django have improved a lot lately. If that is the case, it should be an equally good choice.
