PS: These are notes, there could be grammar error and spelling errors.

Last time had got until here,

We don’t need specify data type with python something similar to javascript where we use var for every type of variable.(const and let are new ES6 standards, although they are not new but new)

So basically

a = 10
b = 1.0
c = "test"

in above a become integer, b becomes float and c becomes string.

Day 1

Installing python

one can install python using package manager depending upon the operating system you are using. As I have a windows machine and ubuntu using linux on windows subsystem. I can install python from https://python.org. And Ubuntu I can use below command to install python.

sudo apt-get install python3

Running python

To run python you would call python3 which open Python interpreter. On that you can type print(“Hello World”) to run your first python code which would print Hello World in next line.

I started to learn Object-oriented Programming in JavaScript using this course. This post is more of notes for the course I am taking.
