Consider the following code segments for mapping first names to the list of corresponding last names
A)
def mapNameToLastNames(data):
namemap = { }
for [first,last] in data:
alist = namemap[first]
alist.append(last)
return namemap
B)
def mapNameToLastNames(data):
namemap = { }
for [first,last] in data:
if first not in namemap:
namemap[first] = [ ]
alist = namemap[first]
alist.append(last)
return namemap
C)
def mapNameToLastNames(data):
namemap = { }
for [first,last] in data:
if first not in namemap:
namemap[first] = [last]
else:
namemap[first].append(last)
return namemap
D)
def mapNameToLastNames(data):
namemap = { }
for [first,last] in data:
if first not in namemap:
namemap[first] = [ ]
namemap[first].append(last)
return namemap
