What is Python?

Filed Under: Python

Python is currently one of the most popular programming languages in the world, with more than 8.2 Million active developers. Often, it is considered as the programming language for the future.

In technical terms, Python is a high-level language, incorporating Object-Oriented Programming concepts.

History of Python Programming

At the National Research Institute for Mathematics and Computer Science in the Netherlands, Python was first developed by Guido van Rossum in 1990. Rossum wanted the name of the new language to be short, unique and mysterious. Certainly, inspired by Monty Python’s Flying Circus, a BBC comedy series, he named it Python.

Certainly, the language became popular, due to its simple, concise and extensive support of libraries. Furthermore, its source code is currently available under the General Public License(GPL) and maintained by the core development team at the same institute.

Why Python?

Different Advantages of using Python has actually made it stand out of the crowd of programming languages including C, C++, C#, Java, etc. Some well-known advantages of Python are,

  1. Readability– Python undoubtedly offers more readability of code compared to the others. Because of the simple and concise syntax. Consequently making it easier to maintain.
  2. Potability– Python is platform-independent and the programs run on any platform.
  3. Vast support of libraries– With a large collection of the in-built standard library functions, Python even supports third party software like NumPy as an extension.
  4. Software Integration– Also, Python is used as an intermediary or agent between two apps. It can easily invoke libraries of other programming languages.
  5. Developer Productivity– Python is even productive due to typically smaller codes. Because of the fact that Python is a dynamically typed language. Hence, it doesn’t need a variable declaration, consequently reducing code size.

Installation

Python is available for almost all operating systems such as Windows, Mac, Linux, etc. Different versions of Python can be downloaded from the official website python.org.

Starting with Different Python Execution Modes

Command Line

Python is an Interpreted language. One can directly write code into the interpreter. Executing Python expressions or statements from the command line takes the user to the interactive mode.

Python IDLE

Using Python IDLE is another way to start the execution of Python statements in the interactive mode of Python IDLE.

Inside the Python, the user can also write a sequence of instructions in one script file and execute them in the Python Script mode.

Internal Working of Python

The Python interpreter performs a series of steps to execute a program and run a set of instructions in the interactive mode.

  1. The interpreter first checks for syntax errors and halts if it encounters one.
  2. After error-free code is processed. The interpreter translates it into a Low-level language called “Byte Code”.
  3. Finally, this Byte code is sent to the Python Virtual Machine(PVM) and hence executed. Also, the execution is halted with an error message if any error occurs.

Applications of Python Programming

The different features of Python programming make it a widely-used programming language. Furthermore, it finds application in various fields

  • Machine learning
  • Artificial Intelligence
  • Game development
