Python Programming -Basics
Python is a widely used high-level programming language for general-purpose programming. Created by Guido van Rossum and first released in 1991.
- Python is interpreted: python is processed at runtime by the interpreter. You do not need to compile your program before executing it. This is similar to PERL and PHP.
- Python is Interactive: You can actually sit at a Python prompt and interact with the interpreter directly to write your programs.
- Python is Object-Oriented: Python supports an Object-Oriented style or technique of programming that encapsulated code within objects.
- Python is a Beginner’s Language: Python is a great language for beginner-level programmers and supports the development of a wide range of applications from simple text processing to WWW browsers to games.
Features of Python
Easy to learn :
Python has few keywords, a simple structure, and a clearly defined syntax. This allows the student to pick up the language quickly.
Easy to read :
Python code is more clearly defined and visible to the eyes.
Easy to maintain :
Python’s source code is more clearly defined and visible to the eyes.
Abroad standard library :
Python’s bulk of the library is very portable and cross-platform compatible with UNIX, Windows, and Macintosh.
Interactive Mode:
Python has support for an interactive mode that allows interactive testing and debugging of snippets of code.
Portable :
Python can run on a wide variety of hardware platforms and has the same interface on all platforms.
Extendable :
You can add low-level modules to the Python interpreter. These modules enable programmers to add to or customize their tools to be more efficient.
Databases:
Python provides interfaces to all major commercial databases.
GUI Programming :
Python supports GUI applications that can be created and ported to many system calls, libraries, and windows systems, such as Windows MFC, Machintosh, and the X Window system of Unix.
Scalable :
Python provides a better structure and support for large programs than shell scripting.
Let’s start with a short simple program given below.
Entering the program
First of all, you must enter the program into your computer using a text editor. The first step is giving the name to the file as you prefer, but the file should be a python file therefore it should be as (.py ). For the above-given example, we can name the file as example1.py.
Executing the program
A python script can be executed at the command line by invoking the interpreter on your application.
C: > python example1.py
By executing the above-mentioned code script we can see this output.
