Which book is the best for introduction to analysis social network using python3 I am a beginner studying social network analysis.
I installed python 3 just 2 weeks ago.
There are a lot of books for python and social network analysis.

I couldn't choose one of them.
I found one book named "Mining the Social Web (Analyzing Data from Facebook, Twitter, Linkedln, and Other Social Media Sites)" written by Matthhew A. Russell.
This book looks very interesting and fits in my purpose, but it is based on python 2. 

Is there any good books with python 3? I usually use Twitter, Facebook, or Blog data.

In addition, could you recommend any good book for nodeXL and UCINET?
Russell's book is fine. You might also like Social Network Analysis for Startups. All the examples are in python. You can do all your analysis in that using packages like networkx. NodeXL is for the Excel crowd. Definitely not the ideal tool for the job; I would shy away from it.

The obvious book for NodeXL is Analyzing Social Media Networks with NodeXL, which is written by the authors of NodeXL.
