Srujan Gaddam f34eef5b91 [dart:html] Migrate python scripts to python 3 
Migrates syntax and semantics from python 2.7.

Major changes include:

- filters
- sorting
- print statements
- higher-order functions
- hashing and comparison

and other misc changes. go.sh consistently gives the libraries
in this and the previous commits with these changes.
