Best Laptops Under rupees 50,000

For programmer it's best to go with the laptops with intel i5 processor which has 4 cores in it with the latest generation.

The minimum RAM required for intel i5 processor is 8GB, and all the laptops with intel i5 processor comes with 8GB of RAM.

For the memory, you can go with HDD or SSD. It's best to go with SSD as it is faster and efficient than HHD. Laptops comes with integrated graphic card.

Learn Python

What is Python?

Python is an interpreted, Object Oriented and high level programming language. Python is an open source programming language that means it is freely available and can be redistributed and modified.

Is Python easy to learn?

Python is an very easy to learn programming language and due to the indentation (TAB space) used in python instead of curly braces makes the program more readable.

Why Python is different from other programming language?

Takes less time to develop.
Very easy to learn.
Python program is shorter than the equivalent program written in other programming languages.
Python is stand-alone programming language.
Everything in Python is an object.
Python is interpreted and dynamically typed language.

Why should I learn Python?

As is every day growing language. Because of Python's efficiency, power and easy to learn and read the code makes Python the most recommended language in the field of machine learning(ML) and Artificial intelligence(AI), which has the wide scope in future and also in the present.

What can You do with Python?

Following are the things, which can be developed using Python.

Desktop applications
Mobile apps
Web apps
Machine Learning(ML) and Artificial Intelligence(AI)
Data Analysis
Automation
Hacking
Testing

Advantages of Python

Free and open source.
Easy to learn .
Dynamically Typed language(No need to specify data type).
Object Oriented Programming language.
Portable across Operating Systems.
Beautiful Data Structures.
User friendly libraries.
Takes few lines of code, even to solve a complex problems.

What is Python best for?

Mostly the Python is used for-

Data Analysis
Artificial Intelligence
Scientific computing

Which industry/companies are using Python?

Following are some top companies who uses Python.

Google
Netflix
NASA
Dropbox
Instagram
Spotify

Who all can use Python?

Data Analysts
Scientists
Mathematicians
Network Engineers
Accountants

Applications of Python

Scientific and Numeric computations.
Desktop GUIs.
Software Development.
Web and Internet Development.
Business Applications.
Machine Learning(ML) and Artificial Intelligence(AI).

Why Python is so popular?

Easy.
Free.
Very useful and user friendly Libraries.
Dynamic, that means no need to specify data type to variables based on the value assigned.
