WebMar 9, 2024 · 2. So yet another Sieve of Eratosthenes in Python 3. The function returns a list of all primes smaller but not equal max_n. The motivation is, as a practice, a simple implementation of the algorithm that is faithful, short, readable and transparent, while still getting a reasonable performance. def primes (max_n): """Return a list of primes ... 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. The multiples of a given prime are generated as a sequence of numbers starting from that prime, with constant …
