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):

Cheers,
