if you use less verbose names, you can do the same thing in less than half
the number of characters, without a single oneliner:
def convert(old):
new = dict(
CODE=old['CODEDATA'],
DATE=old['DATE']
)
if old['CONTACTTYPE'] == 2:
new['CONTACT'] = old['FIRSTCONTACT']
else:
new['CONTACT'] = old['SECONDCONTACT']
return new
