Reasoning behind `from ... import ...` syntax in Python
I always wondered why the syntax for importing specific objects from a module is from module import x, y, z instead of import x, y, z from module. I'm not a native speaker, but isn't the latter more correct/natural? So what's the reason to put the from first? Is it merely to simplyfy the grammer (require less lookahead)? Is it an attemp...

Python: find sequential change in one member of list pairs, report other
There must be a simpler, more pythonic way of doing this. Given this list of pairs: pp = [('a',1),('b',1),('c',1),('d',2),('e',2)] How do I most easily find the first item in adjacent pairs where the second item changes (here, from 1 to 2). Thus I'm looking for ['c','d']. Assume there will only be one change in pair[1] for the entir...
Python: 'Private' module in a package
I have a package mypack with modules mod_a and mod_b in it. I intend the first two to be imported freely: import mypack import mypack.mod_a However, I'd like to keep mod_b for the exclusive use of mypack.
