It is also dynamically-typed because it carries out type-checking at runtime.<\/p>\n<p>It does so to make sure that the type of construct matches what we expect it to be.<\/p>\n<p>The distinctive feature of Python is that it is an <strong>interpreted language<\/strong>.<\/p>\n<p>The Python <strong>IDLE<\/strong> (Integrated Development Environment) executes instructions one line at a time. This also lets us use it as a calculator.<\/p>\n<h3>Why is it called Python?<\/h3>\n<p>Guido van Rossum named it after the comedy group Monty Python. That is why the <em>metasyntactic variables (those we will often use to explain code syntax)<\/em> used here are \u2018spam\u2019 and \u2018eggs\u2019 instead of \u2018foo\u2019 and \u2018bar\u2019.<\/p>\n<h3>History of Python<\/h3>\n<p><a href=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2017\/12\/History-of-Python-1.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-84759\" src=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2017\/12\/History-of-Python-1.jpg\" alt=\"History of Python\" width=\"800\" height=\"550\" srcset=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2017\/12\/History-of-Python-1.jpg 800w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2017\/12\/History-of-Python-1-300x206.jpg 300w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2017\/12\/History-of-Python-1-150x103.jpg 150w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2017\/12\/History-of-Python-1-768x528.jpg 768w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2017\/12\/History-of-Python-1-720x495.jpg 720w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2017\/12\/History-of-Python-1-520x358.jpg 520w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2017\/12\/History-of-Python-1-320x220.jpg 320w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/a><\/p>\n<p>&nbsp;<\/p>\n<ul>\n<li><em>Python <\/em>was conceived in the late <strong>1980s<\/strong> and was named after the <em>BBC TV show Monty Python&#8217;s Flying Circus<\/em>.<\/li>\n<li>Guido van Rossum started implementing <strong>Python at CWI in the Netherlands in December of 1989. <\/strong><\/li>\n<li>This was a successor to the ABC programming language which was capable of<strong> exception handling and interfacing<\/strong> with the Amoeba operating system.<\/li>\n<li>On <strong>October 16 of 2000, Python 2.0 released<\/strong> with many new features.<\/li>\n<li>Then <strong>Python 3.0 was released on December 3, 2008<\/strong>.<\/li>\n<li>Latest version of Python is 3.13.2, released on February 4, 2025<\/li>\n<\/ul>\n<h3>Why Learn Python?<\/h3>\n<blockquote><p><strong>Python is the &#8220;most powerful language you can still read&#8221;, Says Paul Dubois<\/strong><\/p><\/blockquote>\n<p>Python is one of the richest Programming languages.

Easy<\/strong><\/p>\n<p>Python is very easy to learn and understand; any beginner can learn Python easily. When writing code in Python, you need fewer lines of code compared to languages like Java.<\/p>\n<p><strong style=\"font-family: Verdana, Geneva, sans-serif\">b. Interpreted<\/strong><\/p>\n<p>It is interpreted(executed) line by line. This makes the Python program easy to test and debug.<\/p>\n<p><strong style=\"font-family: Verdana, Geneva, sans-serif\">c. Object-Oriented<\/strong><\/p>\n<p>The Python programming language supports classes and objects, and hence it is an object-oriented programming language.<\/p>\n<p><strong style=\"font-family: Verdana, Geneva, sans-serif\">d. Free and Open Source<\/strong><\/p>\n<p>The language and its source code are available to the public for free; there is no need to buy a costly license.<\/p>\n<p><strong style=\"font-family: Verdana, Geneva, sans-serif\">e. Portable<\/strong><\/p>\n<p>Since Python is open-source, you can run it on Windows, Mac, Linux, or any other platform. Your programs will work without any need to change it for every machine.<\/p>\n<p><strong style=\"font-family: Verdana, Geneva, sans-serif\">f. GUI Programming<\/strong><\/p>\n<p>Python is useful to develop GUI (Graphical User Interface) using its <strong>Tkinter library.<\/strong><\/p>\n<p><strong style=\"font-family: Verdana, Geneva, sans-serif\">g. Large Python Library<\/strong><\/p>\n<p>Python provides you with a large standard library.<\/p>\n<p>You can use it to implement a variety of functions without the need to reinvent the wheel every time. Just pick the code you need and continue.<\/p>\n<p>In this Python introduction, we have provided a short description. You must read them in detail at <em><a href=\"https:\/\/data-flair.training\/blogs\/python-future\/\">\u00a0Python Programming Features<\/a><\/em><\/p>\n<p><span style=\"font-family: verdana, geneva, sans-serif\"><strong>h. Cross-Platform and Dynamic Typing<\/strong>\u00a0<\/span><\/p>\n<p>Python <span style=\"font-weight: 400\">Runs on Windows, macOS, Linux, even phones. There is no need to declare variable types in advance.<\/span><\/p>\n<h3>Applications of Python<\/h3>\n<p>Python is easy to pick-up even if you come from a non-programming background. You can look at the code and tell what\u2019s going on.<\/p>\n<p><strong>Talking of Python applications<\/strong>, some of the cool things that you can do are &#8211;<\/p>\n<ul>\n<li>Build a website using Python<\/li>\n<li>Develop a game in Python<\/li>\n<li>Perform Computer Vision (Facilities like face-detection and color-detection)<\/li>\n<li>Implement Machine Learning (Give a computer the ability to learn)<\/li>\n<li>Enable Robotics with Python<\/li>\n<li>Perform Web Scraping (Harvest data from websites)<\/li>\n<li>Perform Data Analysis using Python<\/li>\n<li>Automate a web browser<\/li>\n<li>Perform Scripting in Python<\/li>\n<li>Perform Scientific Computing using Python<\/li>\n<li>Build Artificial Intelligence<\/li>\n<li>Create Audio and Video Applications<\/li>\n<li>Design Computer Aided Design Applications<\/li>\n<\/ul>\n<p>Python isn\u2019t limited to these applications. If you\u2019ve ever used services from brands like YouTube, Dropbox, and Netflix, then you\u2019ve been a consumer of Python.<\/p>\n<p>The search-engine <strong>Google<\/strong> also made great use of this language in its initial stages.<\/p>\n<h3>Python Architecture and Working<\/h3>\n<p>Let&#8217;s now talk about the architecture of python and its usual flow &#8211;<\/p>\n<p><strong style=\"font-family: Verdana, Geneva, sans-serif\">a. Parser<\/strong><\/p>\n<p>It uses the source code to generate an abstract syntax tree.<\/p>\n<p><strong style=\"font-family: Verdana, Geneva, sans-serif\">b. Compiler<\/strong><\/p>\n<p>It turns the abstract syntax tree into Python bytecode.<\/p>\n<p><strong style=\"font-family: Verdana, Geneva, sans-serif\">c. Interpreter<\/strong><\/p>\n<p>It executes the code line by line in a REPL (R<i>ead-Evaluate-Print-Loop) fashion.<\/i><\/p>\n<h3>Python Constructs<\/h3>\n<h4>a. Functions in Python<\/h4>\n<p>A<strong>\u00a0Python<\/strong> <strong>function<\/strong> is a collection of statements grouped under a name. You can use it whenever you want to execute all those statements at a time.<\/p>\n<p>You can call it wherever you want and as many times as you want in a program. A function may return a value.<\/p>\n<p><strong>Benefits of Python Function:<\/strong><\/p>\n<ul>\n<li>It makes programs easy to read.<\/li>\n<li>It helps divide large problems into smaller tasks.<\/li>\n<li>It makes calculations, data processing, etc., simpler.<\/li>\n<\/ul>\n<h4>b. Classes in Python<\/h4>\n<p>As we discussed earlier, Python is an object-oriented language. It supports classes and objects.<\/p>\n<p>A class is an abstract data type. In other words, it is a blueprint for an object of a certain kind. It holds no value.<\/p>\n<p>An object is a real-world entity and an instance of a class.<\/p>\n<p><strong>Benefits of Python Classes:<\/strong><\/p>\n<ul>\n<li>It makes real-world problem-solving easier.<\/li>\n<li>It creates code easily and in an organised manner.<\/li>\n<li>It ensures the data is secure when not needed.<\/li>\n<\/ul>\n<h4>c. Modules in Python<\/h4>\n<p>Python module is a collection of related classes and functions.<\/p>\n<p>We have <a href=\"https:\/\/docs.python.org\/3\/tutorial\/modules.html\">modules<\/a> for mathematical calculations, string manipulations, web programming, and many more.<\/p>\n<p><strong>Benefits of Python modules:<\/strong><\/p>\n<ul>\n<li>The code generated earlier can be reused.<\/li>\n<li>It helps in managing important projects easily.<\/li>\n<li>It reduces the effort of finding and fixing the code easily.<\/li>\n<\/ul>\n<h4>d. Packages in Python<\/h4>\n<p><strong>Python package<\/strong> is a collection of related modules. You can either import a <a href=\"https:\/\/pypi.org\/\">package<\/a> or create your own.<\/p>\n<p><strong>Benefits of Python Packages:<\/strong><\/p>\n<ul>\n<li>It helps in organising huge projects successfully.<\/li>\n<li>It breaks the code into small parts for simple understanding.<\/li>\n<li>The task becomes easier by using the required features.<\/li>\n<\/ul>\n<p>Python has a lot of other constructs. These include control structures, functions, exceptions, etc.<\/p>\n<p><strong>Interested in learning Python in detail?
