Html 3 days,
Css 5 days,
Python 7 days.
For every day I meant around 3 hours.
But this is the time to finish the courses.
I keep learning every day by using them.
For python I fall down to just +50% because I don't use it so much.
When i started i don't know even abc of these
Html = 10days.
Css basic = 5 days
Css Advance(grid,flex,..) = 10days
Js = 20-30 days
Everyday 5-7 hrs and i also included practise time in this.
Bcz one can't learn these without practice.
