Note: When people say arrays in Python, more often than not, they are talking about Python lists.If that's the case, visit the Python list tutorial.. In Python 3, the ordinary / division operator returns floating point values even if both operands are integers, so a different operator is needed for floor division. In the following examples, input and output are distinguished by the presence or absence of prompts (>>> and …): to repeat the example, you must type everything after the prompt, when the prompt appears; lines that do not begin with a prompt are output from the interpreter. Yahoo, Battlefield 2, Civilization 4, NASA, AlphaGene — all of them use Python; see the entire list here. George Boole (1815–1864) developed what is now called Boolean algebra, which is the foundation of the digital logic behind computer hardware and programming languages.Boolean algebra is built around the truth value of expressions and objects (whether they are true or false) and is based in the Boolean operations AND, OR, and NOT. According to Wikipedia : In number theory, a perfect number is a positive integer that is equal to the sum of its proper positive divisors, that is, the sum of its positive divisors excluding the number itself (also known as its aliquot sum). Need for decimal module Before actually putting this module to use, let’s see what precision are we talking about and establish why we need this module actually.
