Python is a general-purpose, high-level programming language. Python is used for web development, Machine Learning, and other cutting-edge software development. Python is suitable for both new and seasoned C++ and Java programmers. Guido Van Rossam has created Python in 1989 at Netherlands’ National Research Institute. Python was released in 1991. C++ is a middle-level, case-sensitive, object-oriented programming language. Bjarne Stroustrup created C++ at Bell Labs. C++ is a platform-independent programming language that works on Windows, Mac OS, and Linux. C++ is near to hardware, allowing low-level programming. This provides a developer control over memory, improved performance, and dependable software. Read through this article to get an overview of C++ and Python and how these two programming languages are different from each other. What is Python? Python is currently one of the most widely used programming languages. It is an interpreted programming language that operates at a high level. When compared to other languages, the learning curve for Python is much lower, and it is also quite straightforward to use. Python is the programming language of choice for professionals working in fields such as Artificial Intelligence, Machine Learning (ML), Data Science, the Internet of Things (IoT), etc., because it excels at both scripting applications and as standalone programmes. In addition to this, Python is the language of choice because it is easy to learn. Because of its excellent syntax and readability, the amount of money spent on maintenance is decreased. The modularity of the programme and the reusability of the code both contribute to its support for a variety of packages and modules. Using Python, we can perform − Features Here is a list of some of the important features of Python − Python Example Take a look at the following simple Python program − In our example, we have taken two variables “a” and “b” and assigning some value to those variables. Note that in Python, we don’t need to declare datatype for variables explicitly, as the PVM will assign datatype as per the user’s input. Output On execution, this Python code will produce the following output − What is C++? C++ is a statically typed, compiled, multi-paradigm, general-purpose programming language with a steep learning curve. Video games, desktop apps, and embedded systems use it extensively. C++ is so compatible with C that it can build practically all C source code without any changes. Object-oriented programming makes C++ a better-structured and safer language than C. Features Let’s see some features of C++ and the reason of its popularity. C++ Example Let’s understand the syntax of C++ through an example written below. In our example, we are taking input for two variables “a” and “b” from the user through the keyboard and displaying the data on the console. Output On execution, it will produce the following output − Learn Python in-depth with real-world projects through our Python certification course.

Both of them have their advantages and disadvantages. In this tutorial, we shall take a closure look at their characteristic features which differentiate one from another. Compiled vs Interpreted Like C, C++ is also a compiler-based language. A compiler translates the entire code in a machine language code specific to the operating system in use and processor architecture. Python is interpreter-based language. The interpreter executes the source code line by line. Cross platform When a C++ source code such as hello.cpp is compiled on Linux, it can be only run on any other computer with Linux operating system. If required to run on other OS, it needs to be compiled. Python interpreter doesn’t produce compiled code. Source code is converted to byte code every time it is run on any operating system without any changes or additional steps. Portability Python code is easily portable from one OS to other. C++ code is not portable as it must be recompiled if the OS changes. Speed of Development C++ program is compiled to the machine code. Hence, its execution is faster than interpreter based language. Python interpreter doesn’t generate the machine code. Conversion of intermediate byte code to machine language is done on each execution of program. If a program is to be used frequently, C++ is more efficient than Python. Easy to Learn Compared to C++, Python has a simpler syntax. Its code is more readable. Writing C++ code seems daunting in the beginning because of complicated syntax rule such as use of curly braces and semicolon for sentence termination. Python doesn’t use curly brackets for marking a block of statements. Instead, it uses indents. Statements of similar indent level mark a block. This makes a Python program more readable. Static vs Dynamic Typing C++ is a statically typed language. The type of variables for storing data need to be declared in the beginning. Undeclared variables can’t be used. Once a variable is declared to be of a certain type, value of only that type can be stored in it. Python is a dynamically typed language. It doesn’t require a variable to be declared before assigning it a value. Since, a variable may store any type of data, it is called dynamically typed. OOP Concepts Both C++ and Python implement object oriented programming concepts. C++ is closer to the theory of OOP than Python. C++ supports the concept of data encapsulation as the visibility of the variables can be defined as public, private and protected. Python doesn’t have the provision of defining the visibility. Unlike C++, Python doesn’t support method overloading. Because it is dynamically typed, all the methods are polymorphic in nature by default. C++ is in fact an extension of C. One can say that additional keywords are added in C so that it supports OOP. Hence, we can write a C type procedure oriented program in C++. Python is completely object oriented language. Python’s data model is such that, even if you can adapt a procedure oriented approach, Python internally uses object-oriented methodology. Garbage

Python is a feature-rich, high-level, interpreted, interactive, and object-oriented scripting language. Python is a versatile and very popular programming language due to its features such as readability, simplicity, extensive libraries, and many more. In this tutorial, we will learn about the various features of Python that make it a powerful and versatile programming language. Python’s most important features are as follows: Easy to Learn This is one of the most important reasons for the popularity of Python. Python has a limited set of keywords. Its features such as simple syntax, usage of indentation to avoid clutter of curly brackets and dynamic typing that doesn’t necessitate prior declaration of variable help a beginner to learn Python quickly and easily. Dynamically Typed Python is a dynamically typed programming language. In Python, you don’t need to specify the variable time at the time of the variable declaration. The types are specified at the runtime based on the assigned value due to its dynamically typed feature. Learn Python in-depth with real-world projects through our Python certification course. Enroll and become a certified expert to boost your career. Interpreter Based Instructions in any programming languages must be translated into machine code for the processor to execute them. Programming languages are either compiler based or interpreter based. In case of a compiler, a machine language version of the entire source program is generated. The conversion fails even if there is a single erroneous statement. Hence, the development process is tedious for the beginners. The C family languages (including C, C++, Java, C# etc) are compiler based. Python is an interpreter based language. The interpreter takes one instruction from the source code at a time, translates it into machine code and executes it. Instructions before the first occurrence of error are executed. With this feature, it is easier to debug the program and thus proves useful for the beginner level programmer to gain confidence gradually. Python therefore is a beginner-friendly language. Interactive Standard Python distribution comes with an interactive shell that works on the principle of REPL (Read – Evaluate – Print – Loop). The shell presents a Python prompt >>>. You can type any valid Python expression and press Enter. Python interpreter immediately returns the response and the prompt comes back to read the next expression. The interactive mode is especially useful to get familiar with a library and test out its functionality. You can try out small code snippets in interactive mode before writing a program. Multi-paradigm Python is a completely object-oriented language. Everything in a Python program is an object. However, Python conveniently encapsulates its object orientation to be used as an imperative or procedural language – such as C. Python also provides certain functionality that resembles functional programming. Moreover, certain third-party tools have been developed to support other programming paradigms such as aspect-oriented and logic programming. Standard Library Even though it has a very few keywords (only Thirty Five), Python software is distributed with a standard library made of large number of modules and packages. Thus Python has out of box support for programming needs such as serialization, data compression, internet data handling, and many more. Python is known for its batteries included approach. Some of the Python’s popular modules are: Open Source and Cross Platform Python’s standard distribution can be downloaded from https://www.python.org/downloads/ without any restrictions. You can download pre-compiled binaries for various operating system platforms. In addition, the source code is also freely available, which is why it comes under open source category. Python software (along with the documentation) is distributed under Python Software Foundation License. It is a BSD style permissive software license and compatible to GNU GPL (General Public License). Python is a cross-platform language. Pre-compiled binaries are available for use on various operating system platforms such as Windows, Linux, Mac OS, Android OS. The reference implementation of Python is called CPython and is written in C. You can download the source code and compile it for your OS platform. A Python program is first compiled to an intermediate platform independent byte code. The virtual machine inside the interpreter then executes the byte code. This behaviour makes Python a cross-platform language, and thus a Python program can be easily ported from one OS platform to other. GUI Applications Python’s standard distribution has an excellent graphics library called TKinter. It is a Python port for the vastly popular GUI toolkit called TCL/Tk. You can build attractive user-friendly GUI applications in Python. GUI toolkits are generally written in C/C++. Many of them have been ported to Python. Examples are PyQt, WxWidgets, PySimpleGUI etc. Database Connectivity Almost any type of database can be used as a backend with the Python application. DB-API is a set of specifications for database driver software to let Python communicate with a relational database. With many third party libraries, Python can also work with NoSQL databases such as MongoDB. Extensible The term extensibility implies the ability to add new features or modify existing features. As stated earlier, CPython (which is Python’s reference implementation) is written in C. Hence one can easily write modules/libraries in C and incorporate them in the standard library. There are other implementations of Python such as Jython (written in Java) and IPython (written in C#). Hence, it is possible to write and merge new functionality in these implementations with Java and C# respectively. Active Developer Community As a result of Python’s popularity and open-source nature, a large number of Python developers often interact with online forums and conferences. Python Software Foundation also has a significant member base, involved in the organization’s mission to “Promote, Protect, and Advance the Python Programming Language“ Python also enjoys a significant institutional support. Major IT companies Google, Microsoft, and Meta contribute immensely by preparing documentation and other resources. Apart from the above-mentioned features, Python has another big list of good features, few are listed below −

Python was developed by Guido van Rossum (a Dutch programmer) in the late 1980s and early nineties at the National Research Institute for Mathematics and Computer Science in the Netherlands. Python is derived from many other languages, including ABC, Modula-3, C, C++, Algol-68, SmallTalk, and Unix shell and other scripting languages. Guido van Rossum wanted Python to be a high-level language that was powerful yet readable and easy to use. Python is copyrighted. Like Perl, Python source code is now available under the GNU General Public License (GPL). For many uninitiated people, the word Python is related to a species of snake. Rossum though attributes the choice of the name Python to a popular comedy series Monty Python’s Flying Circus on BBC. Being the principal architect of Python, the developer community conferred upon him the title of Benevolent Dictator for Life (BDFL). However, in 2018, Rossum relinquished the title. Thereafter, the development and distribution of the reference implementation of Python is handled by a nonprofit organization Python Software Foundation. Who Invented Python? Python was invented by a Dutch Programmer Guido Van Rossum in the late 1980s. He began working on Python in December 1989 as a hobby project while working at the Centrum Wiskunde & Informatica (CWI) in the Netherlands. Python’s first version (0.9.0) was released in 1991.

The primary objective of this revamp was to remove a lot of discrepancies that had crept in Python 2.x versions. Python 3 was backported to Python 2.6. It also included a utility named as python2to3 to facilitate automatic translation of Python 2 code to Python 3. Python 3 provided new syntax, unicode support and Improved integer division. EOL for Python 2.x Even after the release of Python 3, Python Software Foundation continued to support the Python 2 branch with incremental micro versions till 2019. However, it decided to discontinue the support by the end of year 2020, at which time Python 2.7.17 was the last version in the branch. Current Version of Python Meanwhile, more and more features have been incorporated into Python’s 3.x branch. As of date, Python 3.11.2 is the current stable version, released in February 2023.

Python is a high-level, interpreted, interactive and object-oriented scripting language. Python is designed to be highly readable. It uses English keywords frequently where as other languages use punctuation, and it has fewer syntactical constructions than other languages. Python is an open-source and cross-platform programming language. It is available for use under Python Software Foundation License (compatible to GNU General Public License) on all the major operating system platforms Linux, Windows and Mac OS. To facilitate new features and to maintain that readability, the Python Enhancement Proposal (PEP) process was developed. This process allows anyone to submit a PEP for a new feature, library, or other addition. The design philosophy of Python emphasizes on simplicity, readability and unambiguity. Python is known for its batteries included approach as Python software is distributed with a comprehensive standard library of functions and modules. Python’s design philosophy is documented in the Zen of Python. It consists of nineteen aphorisms such as − To obtain the complete Zen of Python document, type import this in the Python Shell − This will produce following 19 aphorisms – Python supports imperative, structured as well as object-oriented programming methodology. It provides features of functional programming as well. Pythonic Code Style Python leaves you free to choose to program in an object-oriented, procedural, functional, aspect-oriented, or even logic-oriented way. These freedoms make Python a great language to write clean and beautiful code. Pythonic Code Style is actually more of a design philosophy and suggests to write a code which is : The Zen of Python The Zen of Python is about code that not only works, but is Pythonic. Pythonic code is readable, concise, and maintainable.
