Introduction to python
- 2. Why Python ? • Python is a high-level, interpreted, interactive and object-oriented scripting language. • It uses English keywords frequently. • Python is a MUST for students and working professionals to become a great Software Engineer specially when they are working in Web Development Domain.
- 3. Key Advantage • Python is Interpreted − Python is processed at runtime by the interpreter. You do not need to compile your program before executing it. • 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 Object-Oriented style or technique of programming that encapsulates code within objects. • Python is a Beginner's Language − Python is a great language for the beginner-level programmers and supports the development of a wide range of applications from simple text processing to WWW browsers to games.
- 4. Characteristic of Python • It supports functional and structured programming methods as well as OOP. • It can be used as a scripting language or can be compiled to byte-code for building large applications. • It provides very high-level dynamic data types and supports dynamic type checking. • It supports automatic garbage collection. • It can be easily integrated with C, C++, COM, ActiveX, CORBA, and Java.
- 5. Applications of Python • Easy-to-learn − Python has few keywords, 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 fairly easy-to-maintain. • A broad standard library − Python's bulk of the library is very portable and cross-platform compatible on UNIX, Windows, and Macintosh.
- 6. Applications of Python • Interactive Mode − Python has support for an interactive mode which 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.
- 7. Applications of Python • 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, Macintosh, and the X Window system of Unix. • Scalable − Python provides a better structure and support for large programs than shell scripting.
