PYTHON PROGRAMMING

For newcomers and beginners, Python is incredibly easy to learn and use because of its simplified syntax with an emphasis on natural language.

Python is the most preferred choice because it is well known for its speed, reliability, and efficiency, elegant syntax and dynamic typing.

About python

Van Rossum started developing the new script in the late 1980s and finally introduced the first version of that programming language in 1991. This initial release has module system of Modula-3. Later on, this programming language was named ‘Python’. Python is a robust programming language and provides an easy usage of the code lines, maintenance can be handled in a great way, and debugging can be done easily too. The syntax in Python helps the programmers to do coding in fewer steps.

Why to prefer Python

Ask any Python developer — or anyone that’s ever used the language — and they’ll agree it’s speedy, reliable and efficient.

Python is interpreted

It is processed at run time by the interpreter. You do not need to compile your program before executing it as we do in PHP and PERL

Applications

The Python language has diversified applications in the software development companies such as in gaming, web frameworks and applications, language development, prototyping, graphic design applications, etc.

Major versions Python 2 and Python 3
