valgrind is what I was going to suggest. You have to compile Python with
extra flags to get it to integrate well with valgrind tho

I don't see why not. It should work on any system

break is not the only way to exit the for loop
Fine - "else if not break or raise or return:"

I don't think I'll ever agree with you on this one.
"then", to me, implies the code following it is always executed.
"else" implies it's conditional.
In those constructs

IIRC, you create it using a list comprehension which creates the
records. A list comprehension always creates a list.
Well no. The list is created with:
records.extend(Record._make(row) for row in rows)
No

Since I won't change the order of the records again after the sort, I'm
using
records.sort(key=operator.attrgetter("Description", "Date"))
once, which also works perfectly.
So both sorted() and sort() can be used to sort namedtuples. Good to
know!
