Never use the input() function in Python 2.x; it does an eval(), which
is evil. Always use raw_input() and an explicit conversion instead;
e.g.
Q = 'Enter the length till which you want to generate the fibonnaci series: \n'
try:
length = int(raw_input(Q))
except ValueError:
print 'Invalid input detected'
exit(0)
Also, as a sidenote:
> if type(length) is int:
Is normally written:
if isinstance(length, int):
