Learn Python Programming Language from Scratch
Coding has become the new literacy for 21st century. Everyone in the 21st century will have to learn to code.
So, what is coding? Coding is basically writing instructions which can be understood by computers to accomplish certain task. Task can be anything like generating prime numbers, sending email to all employee in the organization whose email addresses are stored in excel sheet, detecting human face in given image to auto tagging person in Facebook post by recognizing face from uploaded photo.
Learning to code increases your productivity and it is still a fun creative skill. To code, we need to know programming languages. Programming languages are basic building block for creating software.
Programming languages allow us to write code (instructions) which can be processed or understood by computer.
This course uses the python programming language. Python programming language is the best first language to learn because it has simple elegant syntax and gentle learning curve (you can write and understand python code quickly and easily).
Many universities all over the world are switching their computer science syllabus (curriculum) away from C programming language and Java programming language to Python.
Python is powerful programming language used in the real world applications. Big companies like Google, NASA, Yahoo uses python for various task.
