My favorite language for maintainability is Python. It has simple, clean syntax, object encapsulation, good library support, and optional named parameters.<\/strong>

– Bram Cohen<\/strong><\/p>\r\n<\/blockquote>\r\n

Python is trending now and will remain in the limelight for the next few decades. Everyone wants to learn it and build a career that pays well.<\/p>\r\n

In this Python introduction tutorial, we will talk about history, features, applications, constructs, implementation, and reasons to learn Python.<\/p>\r\n

So, Let\u2019s get started!<\/p>\r\n\r\n\r\n\r\n\r\n\r\n

Python Tutorial<\/h3>\r\n\r\n\r\n\r\n

Python is a general-purpose programming language that is interpreted and high-level. It focusses on readability<\/strong> and simple syntax<\/strong>. It has English like syntax and reading a python code is similar to reading an English sentence.<\/p>\r\n

Python offers all the functionalities one might ever need for programming tasks.<\/p>\r\n\r\n\r\n\r\n

History of Python<\/h3>\r\n\r\n\r\n\r\n

In December 1989, Guido Van Rossum<\/strong> was searching for a hobby project to keep him occupied around Christmas week. Since he had already been planning to write a new scripting language descended from ABC, that would also appeal to Unix\/C hackers<\/strong>, he ended up writing an interpreter for it.<\/p>\r\n

Being a big fan of the British comedy troupe Monty Python, he chose to call the project ‘Python’<\/strong> in an irreverent mood.<\/p>\r\n\r\n\r\n\r\n

Today, it is one of the most widely-used programming languages in the world. The list of top programming languages by the IEEE<\/strong> Spectrum has it at #1<\/strong> and the TIOBE Index<\/strong> has it at #3<\/strong>. It is used for a variety of applications and it\u2019s a very popular language.<\/p>\r\n

Python is now also being used as an introductory language to programming for university students.<\/p>\r\n\r\n\r\n\r\n

Features of Python<\/h3>\r\n\r\n\r\n\r\n
\r\n
\"Features<\/a><\/figure>\r\n<\/div>\r\n\r\n\r\n\r\n

Now in the Python Tutorial, let\u2019s talk about some amazing features<\/strong> of Python programming language:<\/p>\r\n\r\n\r\n\r\n

1. User-Friendly<\/h4>\r\n\r\n\r\n\r\n

Python’s syntax is simple<\/strong>. It’s much like writing in English, and this is why it is easy to read (and understand) and write code in Python. Python code is concise<\/strong>. Unlike Java, you can get things done in less lines of code.<\/p>\r\n

This is Hello, world! in Python:<\/p>\r\n\r\n\r\n\r\n

print(\u201cHello, world!\u201d)<\/pre>\r\n\r\n\r\n\r\n
2. Open-Source and Community<\/h4>\r\n\r\n\r\n\r\n
Python is open-source<\/strong> and its source code is available to the public for free<\/strong>. One great thing about Python is its large community that’s supportive and also always trying to improve it. So if you run into an issue while coding in Python, remember that StackOverflow<\/strong> has over 1,247,320<\/strong> questions for Python.<\/p>\r\n\r\n\r\n\r\n
3. Prototyping<\/h4>\r\n\r\n\r\n\r\n
Because of Python’s simple syntax<\/strong> and readability, developers are more productive and can perform fast prototyping<\/strong>. This gives us the proof-of-concept and project requirements and also tells us about the team’s capabilities. It also gives us the Minimum Viable Product (MVP)<\/strong>.<\/p>\r\n\r\n\r\n\r\n
4. Expressive<\/h4>\r\n\r\n\r\n\r\n
Python is expressive and lets us focus on what we want to do instead of the trivial<\/strong> things.<\/p>\r\n
What’s expressive power? Consider two languages A and B. If all programs in A can be written in B using local transformations, but not all of those in B can be written in A, then B is more expressive than A.<\/p>\r\n\r\n\r\n\r\n
5. Portable<\/h4>\r\n\r\n\r\n\r\n
Code you write on Windows can be transferred to Mac as it is and the other way around. When you write Python code for one machine, you don’t need to make changes to it to run it elsewhere. This is excluding any system-dependent<\/strong> features.<\/p>\r\n\r\n\r\n\r\n
6. High-level<\/h4>\r\n\r\n\r\n\r\n
As we said above, Python is a high-level language<\/strong>. For programmers, there is no need to remember system architecture or manage memory.<\/p>\r\n
Python is also programmer-friendly<\/strong>.<\/p>\r\n\r\n\r\n\r\n
7. Interpreted<\/h4>\r\n\r\n\r\n\r\n
While other languages like Java and C++ are compiled, Python is interpreted<\/strong>. Internally, the source code converts to bytecode.<\/p>\r\n\r\n\r\n\r\n
Python code executes line by line and so is easier to debug<\/strong>. Interpreting does make it slower compared to Java, but the difference is not much when the code is huge.<\/p>\r\n\r\n\r\n\r\n
8. Object-Oriented<\/h4>\r\n\r\n\r\n\r\n
Python is an object-oriented language and also supports functional programming. <\/strong>It can model the real world.<\/p>\r\n
Python supports both object-oriented programming and procedure-oriented programming. And it also supports multiple inheritances (Java doesn’t).<\/p>\r\n\r\n\r\n\r\n
9. Dynamic Typing<\/h4>\r\n\r\n\r\n\r\n
As a programmer, you do not need to declare a data type for a value in advance- this is decided at runtime. This can introduce some overhead at runtime.<\/p>\r\n
Python follows the principle of duck typing<\/strong>: “If it looks like a duck, swims like a duck, and quacks like a duck, then it probably is a duck”.<\/p>\r\n\r\n\r\n\r\n
10. Extensible and Embeddable<\/h4>\r\n\r\n\r\n\r\n
Python is both – extensible and embeddable. You can borrow code from other languages (like C++) to extend Python, and also embed it in code that is in other languages to allow scripting<\/strong>.<\/p>\r\n\r\n\r\n\r\n
11. Large Standard Library<\/h4>\r\n\r\n\r\n\r\n
One of Python’s best features is its large standard library.<\/p>\r\n
Since Python focusses on letting you focus on what’s important, it has thousands of libraries so you don’t have to reinvent<\/strong> the wheel.<\/p>\r\n
These are for everything from regular expressions, documentation generation, image manipulation, unit testing, web browsers, databases, CGI, and email.<\/p>\r\n\r\n\r\n\r\n\r\n\r\n
Python Applications<\/h3>\r\n\r\n\r\n\r\n
Python is everywhere. There is nothing you can\u2019t do with it.<\/p>\r\n
Now in this Python tutorial, Let\u2019s take a quick look at where it finds use.<\/p>\r\n\r\n\r\n\r\n
