I'm not sure there's really a need for the OP to explain 
why...perhaps the data comes from an untrusted (or incompetent) 
source and the routine the OP is asking about is to *create* such 
a list-of-tuples or a dict.

The more important question is what the user/app wants to do when 
such a case is encountered:  do they want to ignore the unpaired 
value, or do they want to pad it with a default value?
