What is Python?

Python is a popular programming language. It was created by Guido van Rossum, and released in 1991.

Python is a general purpose, dynamic, high-level, and interpreted programming language. It supports Object Oriented programming approach to develop applications. It is simple and easy to learn and provides lots of high-level data structures.

Python is easy to learn yet powerful and versatile scripting language, which makes it attractive for Application Development.

It is used for:

  • web development (server-side),
  • software development,
  • mathematics,
  • system scripting.

Java vs Python Program

Unlike the other programming languages, Python provides the facility to execute the code using few lines. For example — Suppose we want to print the “Hello World” program in Java; it will take three lines to print it.
