But that's not guaranteed. It depends on the operating system and file

In Python it's hard to think of many non-trivial problems that you
*don't* have to know about dictionaries.

I don't think that's guaranteed by anything. I realized that
'dat.sort()' and 'txt.sort()' weren't necessary, since their contents
are moved to a dictionary, which isn't sorted.
Actually, I'm getting the file names from listdir, and they appear to be
sorted low to high.
D,T=[dict((x.split('.')[0],x) for x in X) for X in (dat,txt)]
for k in sorted(set(D).union(T)) :
for S in D,T :
print '%-8s' % S.get(k,'None'),

Maybe there's some function like zip or map that does this. If not, it's
probably fairly easy to do with push and pop. I'm just checking to see if
there's not some known simple single function that does what I want. Here's
what I'm trying to do.
I have a list dat like (assume the items are str
