Introduction

python is a widely used general-purpose, high level programming language. It was created by Guido van Rossum in 1991 and further developed by the Python Software Foundation. It was designed with an emphasis on code readability, and its syntax allows programmers to express their concepts in fewer lines of code.

Python is a programming language that lets you work quickly and integrate systems more efficiently.

There are two major Python versions: Python 2 and Python 3. Both are quite different.

Beginning with Python programming:

1) Finding an Interpreter:

Before we start Python programming, we need to have an interpreter to interpret and run our programs. There are certain online interpreters like https://ide.geeksforgeeks.org/, http://ideone.com/ or http://codepad.org/ that can be used to run Python programs without installing an interpreter.

Windows: There are many interpreters available freely to run Python scripts like IDLE (Integrated Development Environment) that comes bundled with the Python software downloaded from http://python.org/.

Linux: Python comes preinstalled with popular Linux distros such as Ubuntu and Fedora. To check which version of Python you’re running, type “python” in the terminal emulator. The interpreter should start and print the version number.

macOS: Generally, Python 2.7 comes bundled with macOS. You’ll have to manually install Python 3 from http://python.org
 

Below are some facts about Python Programming Language:

  1. Python is currently the most widely used multi-purpose, high-level programming language.
  2. Python allows programming in Object-Oriented and Procedural paradigms.
  3. Python programs generally are smaller than other programming languages like Java. Programmers have to type relatively less and indentation requirement of the language, makes them readable all the time.
  4. Python language is being used by almost all tech-giant companies like – Google, Amazon, Facebook, Instagram, Dropbox, Uber… etc.
  5. The biggest strength of Python is huge collection of standard library which can be used for the following:
    • Machine Learning
    • GUI Applications (like Kivy, Tkinter, PyQt etc. )
    • Web frameworks like Django (used by YouTube, Instagram, Dropbox)
    • Image processing (like OpenCV, Pillow)
    • Web scraping (like Scrapy, BeautifulSoup, Selenium)
    • Test frameworks
    • Multimedia
    • Scientific computing
    • Text processing and many more..

 Artificial intelligence What is artificial intelligence? Artificial intelligence is the simulation of human intelligence processes by machines, especially computer systems. Specific applications of AI include expert systems , natural language processing, speech recognition and machine vision . How does AI work? As the hype around AI has accelerated, vendors have been scrambling to promote how their products and services use AI. Often what they refer to as AI is simply one component of AI, such as machine learning . AI requires a foundation of specialized hardware and software for writing and training machine learning algorithms. No one programming language is synonymous with AI, but a few, including Python, R and Java, are popular. In general, AI systems work by ingesting large amounts of labeled training data, analyzing the data for correlations and patterns, and using these patterns to make predictions about future states. In this way, a chatbot that is f...

  Meteorite-hunting drones could help find freshly fallen space rocks Meteorite are among the most important objects scientists can study to understand the solar system, but finding them is tricky and time-consuming. Now, one team of researchers is trying to speed up the process with drones. Robert Citron at the University of California, Davis, and his colleagues have been trialling using drones and machine learning to find these rocks shortly after their blazing journey through the atmosphere. The NASA-funded study flew a camera-equipped consumer drone over a dry lake bed in Nevada, … Read more: https://www.newscientist.com/article/2281804-meteorite-hunting-drones-could-help-find-freshly-fallen-space-rocks/#ixzz6zcmRBwFk

  Israel used world's first AI-guided combat drone swarm in Gaza attacks     During operations in Gaza in mid-May, the Israel Defense Forces (IDF) used a swarm of small drones to locate, identify and attack Hamas militants. This is thought to be the first time a drone swarm has been used in combat. Drones are usually controlled individually by remote operators, but a swarm is a single networked entity that flies itself using artificial intelligence . It can cover a wide area and keep operating even if it loses many units, and only requires a single … Read more: https://www.newscientist.com/article/2282656-israel-used-worlds-first-ai-guided-combat-drone-swarm-in-gaza-attacks/#ixzz6zckcR3Ql
