I thought I had the difference between 'zip' and 'map' sorted but when
I try to fill missing entries with something other than 'None'. I do
not seem to be able to get it to work - any pointers appreciated.

lista = ['a1', 'a2']
listb = ['b10', 'b11','b12' ,'b13']
for x,y in zip(lista, listb): # Fine Truncates as expected
print "ZIP:", x, "<<x y>>", y
for x,y in map(None, lista, listb): # Also fine - extends as
expected
print "MAP:", x, "<<x y>>", y
for x,y in map("N/A", lista, listb): ########## Fails - Can not call a
'str'
print "MAP:", x, "<<x y>>", y
def fillwith(fillchars):
return fillchars
for x,y in map(fillwith("N/A"), lista, listb): ########## Fails also -
Can not call a 'str'
print "MAP:", x, "<<x y>>", y
