WebDec 29, 2014 · Out of curiosity, I built a recursive Sieve of Eratosthenes in Python and I was wondering how it could be improved for efficiency and how it can improved to be aligned with python best practices. Essentially, there is a recursive function (coded horrendously IMO), filter_multiples , which removes the multiples of some number. WebThe Sieve of Eratosthenes in Python. Recap problem: Write an algorithm that is more efficient than the above naïve implementation to find all prime numbers up to a maximal integer number m. This one-liner is inspired by an ancient algorithm called “the Sieve of Eratosthenes” which will be explained in the remainder of this section. WebIn mathematics, the sieve of Eratosthenes is an ancient algorithm for finding all prime numbers up to any given limit.. It does so by iteratively marking as composite (i.e., not prime) the multiples of each prime, starting with the first prime number, 2.
