## HTML nutshell
HTML quottation --> same as medium quotation
HTML image map --> Create the clickable areas on the image
Add icon to webpage --> HTML favicon
p and div vs when to use span --> p when we want to occupy new line vs span dont start in new line and dont add extra space
class vs id --> class can be assigned to many elements but id wont
<details> --> To provide small information in the form of widget
<figcaption> --> To provide the caption to the figure
&nbsp --> To add extra space ; &lt (less than) ; &gt (greater than) ; &amp (ampersand)

shift + F6 --> refactor or rename variable with all occurence
ctr + alt + v --> convert expression to variable
ctr + alt + m --> convert expression to function
ctr + alt + l --> reformat the code

## Installing and creating python env
1. Installation
sudo apt-get install python3.x
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python3.x get-pip.py
