Python is a generally interpreted and interactive dynamic symmetric high-level object oriented programming language. It is widely used in Machine Learning today. Pretty easy to understand, learn, code and explain because it has very crisp and clear syntaxes than other languages.
Guido van Rossum made Python in 1991, named his programming language after the television show Monty Python's Flying Circus. Python has got features or derived features from ABC named programming language.
Interactive
- The result will be
printed on the screen, immediately return, in the next line as we entered.
High-level
- Humans can easy to
interpret; the source code contains easy-to-read syntax that is later converted
into a low-level language (0 , 1)
Dynamic-symmetric – Don’t need to clarify the data
type. It Allows the type casting.
Type
Casting – We can transform the one data type in another
data type
Object
Oriented – language
is focused on Objects which are created using Class. OOP mainly used to binding
the data and functions that operate on and no other type of
code can access this data. All in python language are objects.
Keyword – DRY (Don’t Repeat Yourself)
· Why should use OOPS : for saving time and effort
Class can be described as an object's
blueprint for creating multiple different objects.
Object – Instance of class; it has attributes and behavior. take water as an example of object. It has weight, color, fluidity are its definite attributes. And apparently it has behavior like flowing, boiling, freezing etc. These are same things the behaviors of object are called method in object oriented programming language.
Object-oriented programming is based on the following:
Encapsulation - The state of each object are
privately held inside a class. Other objects do not have access to this class.
Abstraction - use for hiding any unnecessary
implementation code and helps developers more easily make changes and additions
over time.
Inheritance – A class which inherits the
properties of another class
Polymorphism - Objects can take on more than one
form depending on the context. Child class can be given same name as Parent
class.
Here some of the features of Python are
a) It is an open source programming language
b) Interpreted Language.
c) More expressive so that is simple and easy to learn, read and execute the syntax
d) developing desktop GUI applications website and web applications,
e) Provide the large Standard Library.
f) Directly runs from the source code. Not need to compile.
Why python is the best choice for Web based Programming today?
Today we have more data and processing power than before. Until today we have created 100 Exabytes of data via social mediums so yes the Python is best choice for Web based Programming because of its great features. like it is easiest to learn, read and fastest workflow with much lesser coding, The main reason is it integrates easily with other languages just like Java, C++, or C and it is open source, freely available, and quite stable. Its standard library support enables to execute a lot of complex functionalities easily. Its provide the security and large advanced library
Why python is called interpreted language?
Python is called an interpreted language because it goes through an
interpreter called PVM (Python Virtual Machine), which converts the written code line by line direct into the machine code language which direct understood by computer's processor. As we don't need to compile codes by own self.
