Here's a simplistic implementation:
----------------------------------------------
#!/usr/local/bin/python
k = ["one","two","three"]
v = [1,2,3]
d = {}
n = 0
for i in k:
d[i] = v[n]
n = n + 1
print "Keys:", k
print "Values:", v
print "Dictionary:", d
----------------------------------------------
Alternatively, you could take the list of pairs (tuples) you get back
from map() and iterate over that:
for i in pairs:
dict[i[0]] = i[1]
