2. What Is Python ?
Python is a popular programming Language. python is
dynamic,high-level ,interpreated programming language .
It was created by Guido Van Rossum and released in 1991.
It is simple and easy to learn and provides lost of high-level data
structures.
It is used for :
1) web development (server-side),
2)software development,
3)mathematics,
4)system scripting.
3. Why Python?
Python works on different platforms (Windows, Mac, Linux, Raspberry Pi, etc).
Python has a simple syntax similar to the English language.
Python allows a developer to write programs with fewer lines than some other
programming languages.
Python runs on an interpreter system, means that the code can be executed as
soon as it is written. It helps to provide a prototype very quickly.
Python can be treated in a procedural way, an object-oriented way or a functional
way.
4. Application Of python
Python is used in various software domains some application areas are given below:
Web and Internet Development
Games
Scientific and computational applications
Language development
Image processing and graphic design applications
Enterprise and business applications development
Operating systems
GUI based desktop applications
5. Advantages of Python
Interpreted: Python is an interpreted language. It does not require prior
compilation of code and executes instructions directly.
Free and open source: It is an open source project which is publicly available to
reuse. It can be downloaded free of cost.
Portable: Python programs can run on cross platforms without affecting its
performance.
Extensible: It is very flexible and extensible with any module.
Object-oriented: Python allows to implement the Object Oriented concepts to
build application solution.
Built-in data structure: Tuple, List, and Dictionary are useful integrated data
structures provided by the language.
6. Different Between Python 2 and Python 3
Python 2
Released in 2000
Function print: print “hello”
User input: raw_input() function use.
implicit string type is ASCII
Xrange() function is used for iterations.
Ex.
print “hello world”
Python 3
Released in 2003
Function print: print(“hello”)
User input: input() function use.
Implicit string type is Unicode.
Range() function is used for
iterations.
Ex.
Print(“hello world”)
7. Python comments
Comments can be used to explain Python code.
Comments can be used to make the code more readable.
Comments can be used to prevent execution when testing code.
Comments start with # .
Ex.
#this is example
Print(“hello world”)
