I wanted to get feedback on my answer to question #4, as the way I coded it seems to work but seems much different from the solution provided.
def first_N(n):
if n <= 0:
print 'Must enter a positive integer'
else:
for intnum in range(n*2):
intnumsq = intnum * intnum
if intnumsq%2 != 0: # if intnum is odd number
print intnumsq
