gramps/src/plugins/export/ExportVCalendar.py
Gerald Britton 8f0582df8a Use built-in functions to replace for loops: 
Old code:

for x in y:
  f(x)

New Code:

map(f, y)

Also use defaultdict instead of simple dict when advantageous and use list comprehensions
instead of for loops where map() could be used but requires lambdas.
