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.
This is why the next missile built by Rafael in early 1970s was named Python-3, but there is no Python-1 or Python-2 (they were Shafrir-1, Shafrir-2). The Python-3 has improved range and all-aspect attack ability, it proved itself before and during the 1982 Lebanon War , destroying 35 enemy aircraft.
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.
Python 2.6 was released to coincide with Python 3.0, and included some features from that release, as well as a "warnings" mode that highlighted the use of features that were removed in Python 3.0. [ 28 ] [ 10 ] Similarly, Python 2.7 coincided with and included features from Python 3.1, [ 29 ] which was released on June 26, 2009.
From 2005 to December 2012, Van Rossum worked at Google, where he spent half of his time developing the Python language. At Google, he developed Mondrian, a web-based code review system written in Python and used within the company. He named the software after the Dutch painter Piet Mondrian. [20]
The Pythian Games supposedly start with the death of the mythical serpent, Python. Ovid states that the games were inaugurated to celebrate Apollo's killing of the serpent, "Lest in a dark oblivion time should hide the fame of this achievement, sacred sports he instituted" (Metamorphoses, 1.445-6).

If there are no columns or other divisions but there are regularly-spaced windows, each window in a wall is counted as a bay. For example, Mulberry Fields, a Georgian style building in Maryland, United States, is described as "5 bay by 2 bay," meaning "5 windows at the front and 2 windows at the sides". A recess in a wall, such as a bay window. [2]
