It could e.g. look like this in Python:

stoogeGuys = []
for xmlGuys in xmlSource.Desce ndants["Stooge"]:
arrayGuys = familyFacts[xmlGuys.stoogeN ame]
dbGuys = stoogeContext.s toogeTables[xmlGuys.stoogeN ame]
stoogeGuys += \
[{'firstName': dbGuys.stoogeNa me,
'familyName': arrayGuys.famil yName,
'birthDate': xmlGuys.birthDa te,
'deathDate': dbGuys.deathDat e,
'hairCutStyle': dbGuys.stoogeHa ircut}]

It's more Pythonic to use the syntax of dictionary lookups.
