Problem 1
Part A

index+2 skips the comma and space to get the first name
the slice uses index to get everything up to and NOT including the comma


Part B

.find() returns -1 when the string is not found, so -1+2 = 1 and the
slice gets "ob jones". The value of the slice "bob jones"[:-1] is
everything up to and not including the last character or "bob jone"


Problem 2
Part A

def is_abundant (num):
   total = 0
   for n in range(1, num):
       if num % n == 0:
           total = total + n
   return total > num

#
# OR
#
def is_abundant (num):
   total = sum([ n for n in range(1,num) if num % n == 0 ])
   return total > num


Part B

def abundant_count (start, end):
   total = 0
   for n in range(start, end+1):
       if is_abundant(n):
           total += 1
   return total

#
# OR
#
def abundant_count (start, end):
   return len([ x for x in range(start,end+1) if isabundant(x) ])



Problem 3

def getAgeList(filename, low, high):
   f = open(filename)
   results = [ ]
   for line in f.readlines():
       data = line.split(",")
       age = int(data[2])
       if low <= age <= high:
           results.append(data[0])
   f.close()
   return results
