Just wanting to ease your concerns down some more; Having taken version 3 of the course and looking at your relevant experience listed of what you've toyed with, you should be good to go. The course has some python and bash scripting in it, and some of the exercises have been tailored to fit your appropriate scripting language needs. Like for example, a couple exercises that may involve programming give you the option of scripting language to complete it in.
Andrew Waite was right on the spot though with his response - I just wanted to help you feel more at ease. Pythons great!
