Sieve of Eratosthenes: algorithm steps for primes below 121 (including optimization of starting from prime's square). In mathematics, the sieve of Eratosthenes is an ancient algorithm for finding all prime numbers up to any given limit.
Eratosthenes was the founder of scientific chronology; [5] he used Egyptian and Persian records to estimate the dates of the main events of the Trojan War, dating the sack of Troy to 1183 BC. In number theory , he introduced the sieve of Eratosthenes , an efficient method of identifying prime numbers and composite numbers.
Python 2.1 was close to Python 1.6.1, as well as Python 2.0. Its license was renamed Python Software Foundation License . All code, documentation and specifications added, from the time of Python 2.1's alpha release on, is owned by the Python Software Foundation (PSF), a nonprofit organization formed in 2001, modeled after the Apache Software ...
In December 2021, a Burmese python was captured in Florida that weighed 98 kg (215 lb) and had a length of 5.5 m (18 ft); it contained a record 122 developing eggs. [41] In July 2023, local hunters captured and killed a 5.8 m (19 ft) long Burmese python that weighed 57 kg (125 lb) in Florida's Big Cypress National Preserve. [14]
The following is pseudocode which combines Atkin's algorithms 3.1, 3.2, and 3.3 [1] by using a combined set s of all the numbers modulo 60 excluding those which are multiples of the prime numbers 2, 3, and 5, as per the algorithms, for a straightforward version of the algorithm that supports optional bit-packing of the wheel; although not specifically mentioned in the referenced paper, this ...
Python, sometimes written Pytho, presided at the Delphic oracle, which existed in the cult center for its mother, Gaia, "Earth", Pytho being the place name that was substituted for the earlier Krisa. [1] Greeks considered the site to be the center of the Earth, represented by a stone, the omphalos or navel, which Python guarded.
The reticulated python is the largest snake native to Asia. More than a thousand wild reticulated pythons in southern Sumatra were studied, and estimated to have a length range of 1.5 to 6.5 m (4 ft 11 in to 21 ft 4 in), and a weight range of 1 to 75 kg (2 lb 3 oz to 165 lb 6 oz). [27]
Author Martin Dougherty notes the weight of the Python as a drawback, as it is quite heavy for a handgun of its caliber, ranging from 2.4 lbs (1.1 kg) to 2.6 lbs (1.2 kg). This makes the Python comparable to Smith & Wesson's premier .357, the M27, which weighs 2.6 lb (1.2 kg) with a 4-inch (10 cm) barrel. Both revolvers are 6 to 9 ounces (170 ...
