In that case you can definitely omit the middle term of the slice,
which will be both more concise and clearer
Because I want the code to work with Python 3 also, the code is now:
def lucky_numbers(n):
Lucky numbers from 1 up-to n
http://en.wikipedia.org/wiki/Lucky_number
if n 3:
return [1]
sieve = list(range(1, n + 1, 2))

I wrote a function lucky_numbers:
def lucky_numbers(n):
if n 3:
return [1]
sieve = range(1, n + 1, 2)
sieve_index = 1
while True:
skip_count = sieve[sieve_index]
sieve_len = len(sieve)
if sieve_len skip_count:
