I've already learned one neat trick to collapse a conditional:
a = expression1 if condition else expression2
Here I have a real mess, in my opinion:
if len(l1[st]) == 0:
if len(l2[st]) > 0:
l1[st] = l2[st]
elif len(l2[st]) == 0:
if len(l1[st]) > 0:
l2[st] = l1[st]
(Basically, if one field from two adjacent rows is empty and the other
is
not, copy the non-empty field to the empty one. I use this for rental
listings that are identical but posted on different dates, to copy the
data from an older one to the new one. Or, if I look up the data for a
new
listing, to copy it back to the older ones.)
Anybody know or see an easier (more pythonic) way to do this? I need to
do it for four fields, and needless to say, that's a really long block
of ugly code.
Any other insights into tightening up complex conditionals?
Thanks in advance,
Deborah
