Features of Python:(PYTHON FUNDAMENTALS)

Created with Sketch.

1) Simple and easy to learn:

  •  Python is a simple programming language. When we read Python programs, we can feel
    like reading English statements. 
  • The syntaxes are very simple and only 30+ keywords are available.
  •  When compared with other languages, we can write programs with a very less number
    of lines. Hence more readability and simplicity.
  •  We can reduce the development and cost of the project.

 

2) Freeware and Open Source:

  •  We can use Python software without any license and it is freeware.
  • Its source code is open so that we can customize based on our requirements.
  •  Eg: Jython is a customized version of Python to work with Java Applications.

3) High-Level Programming language:

  •  Python is high-level programming language and hence it is programmer friendly
    language.
  •  Being a programmer we are not required to concentrate low-level activities like
    memory management and security etc.

 

4) Platform Independent:

  •  Once we write a Python program, it can run on any platform without rewriting once
    again.
  • Internally PVM is responsible to convert into machine-understandable form.

5) Portability:
Python programs are portable. ie we can migrate from one platform to another
platform very easily. Python programs will provide the same results on any platform.

 

6) Dynamically Typed:

  •  In Python, we are not required to declare the type of variables. Whenever we are
    assigning the value, based on the value, the type will be allocated automatically. Hence Python
    is considered a dynamically typed language.
  •  But Java, C etc are Statically Typed Languages b’z we have to provide type at the
    beginning only.
  • This dynamic typing nature will provide more flexibility to the programmer.

7) Both Procedure Oriented and Object Oriented:
Python language supports both Procedure oriented (like C, pascal etc) and object
oriented (like C++, Java) features. Hence we can get benefits of both like security and
reusability etc.

 

8) Interpreted:

  • We are not required to compile Python programs explcitly. Internally Python
    interpreter will take care that compilation.
  •  If compilation fails interpreter raised syntax errors. Once compilation success then
    PVM (Python Virtual Machine) is responsible to execute.

 

9) Extensible:

  •  We can use other language programs in Python.
  • The main advantages of this approach are:
    1. We can use already existing legacy non-Python code
    2. We can improve the performance of the application

10) Embedded:
We can use Python programs in any other language programs.
i.e we can embed Python programs anywhere.

11) Extensive Library:

  •  Python has a rich inbuilt library.
  •  Being a programmer we can use this library directly and we are not responsible to
    implement the functionality. Etc.

Limitations of Python:
1) Performance wise not up to the mark because it is interpreted language.
2) Not using Mobile Applications.
