Learning Python
I started by journey of learning Python from Eric Matthes.
The name of the book is Python Crash Course. It give me the necessary start.
I was stuck and asked him a query. He responded immediately.
Later I found Python Data Science Handbook very useful.
It is written by Jake VanderPlas.
To learn pandas, I bought a book by Daniel Y. Chen.
The name of the book is Pandas for Everyone.
Recently I found the articles by Kimberley Fessel to be very useful.
I learned about her excellent articles through a padcast.
If I am not mistaken I heard Daniel Y. Chen on the same podcast channel.
All of the above are very well-know. But still I hope this information helps.
