 Python is a widely used high-level programming language for general-purpose programming, created by Guido van Rossum and first released in 1991. Python features a dynamic type system and automatic memory management and supports multiple programming paradigms, including object-oriented, imperative, functional programming, and procedural styles. It has a large and comprehensive standard library. Two major versions of Python are currently in active use: Python 3.x is the current version and is under active development. Python 2.x is the legacy version and will receive only security updates until 2020. No new features will be implemented. Note that many projects still use Python 2, although migrating to Python 3 is getting easier. You can download and install either version of Python here. See Python 3 vs. Python 2 for a comparison between them. In addition, some third-parties offer re-packaged versions of Python that add commonly used libraries and other features to ease setup for common use cases, such as math, data analysis or scientific use.

Mobile technology learning

Mobile technology is the technology used for cellular communication. Mobile code division multiple access (CDMA) technology has evolved rapidly over the past few years. Since the start of this millennium, a standard mobile device has gone from being no more than a simple two-way pager to being a mobile phone, GPS navigation device, an embedded web browser and instant messaging client, and a handheld game console. Many experts argue that the future of computer technology rests in mobile computing with wireless networking. Mobile computing by way of tablet computers are becoming more popular. Tablets are available on the 3G and 4G networks.

The  Dragunov sniper rifle  (formal  Russian :  Снайперская Винтовка системы Драгунова образца 1963 года Snayperskaya Vintovka sistem'y Dragunova obraz'tsa 1963 goda (SVD-63), officially "Sniper Rifle, System of Dragunov, Model of the Year 1963") is a  semi-automatic   sniper / designated marksman rifle  chambered in  7.62×54mmR  and developed in the Soviet Union . The Dragunov was designed as a  squad  support weapon since, according to  Soviet and Soviet-derived military doctrines , the long-range engagement ability was lost to ordinary troops when submachine guns  and  assault rifles  (which are optimized for close-range and medium-range, rapid-fire combat) were adopted. For that reason, it was originally named Самозарядная Винтовка системы Драгунова образца 1963 года "Self-Loading Rifle, System of Dragunov, Model of the Year 1963". It was selected as the winner of a contest that included three competing designs: by  Sergei Simonov , Aleksandr Konst

Compact stun guns

The compact handheld stun guns are about the size of a TV remote or calculator, and they must touch the subject when used. The original XR-5000 design in 1983 had the electrodes spread farther apart to make the noisy electric arc between the electrodes as a more visible warning. Some such devices are available disguised as other objects, such as umbrellas,  mobile phones  or pens. Electric shock prods Electric cattle prod from the 1950s The larger  baton-style  prods are similar in basic design to an electric  cattle prod . It has a metal end split into two parts electrically insulated from each other, or two thin projecting metal  electrodes  about 2.5 centimetres (1 in) apart, at an end of a shaft containing the batteries and mechanism. At the other end of the shaft are a handle and a switch. Both electrodes must touch the subject. In some types the sides of the baton can be electrified to stop the subject from grasping the baton above the electrodes. Some models are
