1) Using list comprehensions, make me a list of all odd numbers 1 .. 999.  You may use the range(0,2000) function but no other range.

2) Using a reduce, add up the numbers 1 .. 100.

3) Using filter, make me a list of every number that is a multiple of 5 or 3.

4) Using map and range, make me a list of letters.
Hint:  
	chr(97) == 'a'
	chr(97+26) = 'z'

5) Using some array slice operations, make me a list of the integers 100 ... 200 and 300...400.  You may use range(0,1000) but no other use of range.

6) Using some set operations, make me a set of the integers 100 ... 200 and 300...400.  You may use set(range(0,1000)) but no other use of range.

7) Using a dictionary, make a program that reads in names.  When a duplicate appears, print "Eeek" and exit.
Hints:
   # read a name
   name = raw_input("Enter a name")
   # initialize a dictionary
   dict = {}
   # membership testing
   if "name" in dict:
