1. Learn to use the interpreter interactively; ie (at the least)¹ ie
a. Start up python (without a program)
b. Play around with trivial expressions
c. Explore introspective features - help(), type() dir()
2. Do you know about triple-quoted strings?
a. Start small (or trivial) sub-parts of your XML as triple-quoted examples in the
interpreter and start throwing them at elementtree
b. If they dont work trivialize further; if they work add complexity
¹ At the least because environments like Idle are more conducive to such playing
