WHAT IS PYTHON
Python is a high-level, interpreted, interactive and object-oriented scripting language developed by Guido Van Rossum.
Python is a powerful, flexible and easy to use scripting language.
FEATURES OF PYTHON:
Free & Open Source
Python language is freely available at the official website, and we can download it. Since it is open-source, this means that source code is also available to the public. So we can download it, use it as well as share it.
Easy To Learn:
Easy To Read:
Learning Python is quite simple. Python’s syntax is straightforward. And also the code block is defined by the indentations rather than by semicolons or brackets, which makes it easy to read.
Dynamically Typed Language:
Python is a dynamically typed language, i.e. we do not need to declare the datatype of the variable we declare. It is decided at the runtime by the python interpreter.
Ex. if we declare a variable in python, we do not need to specify the type of the data that is to store in that variable like int, float, long etc.
A high-level programming language is a programming language that enables a programmer to write programs that are more or less independent of a particular type of computer. Python is said to be high level since they are very close to human languages and far away from machine languages. This makes debugging easy.
Large Standard Library:
Python has a large standard library collection. One of the main features that made python so famous is that it provides many modules like itertools, operators, math and functions so that you don’t need to write your own code every time while writing the code.
Python supports various programming paradigms like functional programming, and object-oriented programming. It allows users to implement the concepts of classes,
Objects, Encapsulation, Polymorphism, Inheritance and Abstraction.
This consists of access specifiers, which helps to secure data from unauthorized access.
Python is platform independent or portable language, i.e. if we write a python code for mac that will run the on a different platform like windows, Linux without changing the code. That means we don’t need to write different codes for different platforms.
Extensible And Embeddable:
Python is an extensible language that means we can extend our code to other programming languages like c,c++ etc.
Python is an embeddable language. That is we can write a python code into c or CPP and compile that written code in c or c++ programming language
Supports Graphical User Interface:
We can use python programming language to create Graphical User Interface. Python consists of many GUI frameworks.GUI can be made using modules PyQt,Tkinter,wxpython.
APPLICATIONS OF PYTHON
- Web Development
- Data Science And Data Visualization
- Artificial Intelligence And Machine Learning
- Web Scraping
- Business Applications
- Software Development
- Desktop Gui Applications
- Embedded Applications
- Image Processing Applications
LIMITATIONS OF PYTHON:
Slow Execution Speed:
The execution speed of the python program is slow as compared to c /java/c++.python uses an interpreter that will execute the instructions one after the other, which causes it to slow down. Whereas c/c++/java uses a compiler where the entire program is executed
Python programs consume more memory compared to other languages because of the flexibility in its data types.
Game And Mobile Development:
The usage of python in both mobile development and game development is low because of some reasons. One of the main reasons is its slow execution speed compared with the java and c++.
Difficulty In Learning Another Language:
Once you get comfortable with the python programming language, you feel a little difficult while learning other programming languages.
Flavors of Python:
Pypy – Used for increase in the performance
jython or jpython – Used for java applications
Iron python – It is for c# platform or .net platform
Ruby python – Used for the ruby platforms.
Anaconda python – Designed for handling large amounts of data processing.
cpython – Standard flavor of python, used to work with c language applications.
