x = 0.0
for i in range(n, 0, -1):
if i % 3 == 1:
j = int(i / 3) * 2
else:

x = 1.0 / (x + j)

Great! Here is another way of doing this. Also works for e, pi, sqrt(n) [n can be any integer not just 2 or 3]. Let me know if you want the code or explanation

It looks like it is calculating digits of e one by one. Definitely more impressive than my examples :-)

You could just print the result this way though:

print result[0] + "." + result[1:]
