Example: 
from struct import calcsize 
calcsize('h') reports 2 
calcsize('i') reports 4, but 
calcsize('hi') reports 8! (same with calcsize('hhi')) 
 
Am I missing something or isn't it the case that calcsize('h') should 
report 4?

struct defaults to "native" alignment.  Try starting your
format string with "=".

This is documented, so closing.
