* So - what did we learn yesterday?

 - zip, collections
 - dict, set - seventh grade math venn diagram, uniqueness,
   namedtuple, Counter, defaultdict, dict.fromkeys()
   
 - else on loops (don't do this!), for is the one true way
 to loop, break/continue
 
 - functions:
   - *args
   - types of parameters/arguments
   - scope (locals()/globals())
   - global
   - return (implicitly None)
   - are objects, just like everything else
