It provides data structures and functions that make working with structured data, such as tabular data (like Excel spreadsheets orSQL tables), easy and intuitive. Although not best known for this functionality, Pandas can be used to create graphs and visualize data, thanks to its lightweight syntax and matplotlib functions

## Example 2.1 from Dive Into Python - Post author: mikal - Post published:November 29, 2005 - Post category: Python I’ve just started working through Dive Into Python , so I don’t really have an opinion of the book yet. I did notice that Example 2.1 produces different output on my machine than from the example… The example says I should get: - server=mpilgrim;uid=sa;database=master;pwd=secret I get: - pwd=secret;database=master;uid=sa;server=mpilgrim It’s interesting that this is exactly the
Drawing sequentially represented binary trees in Python # Drawing sequentially represented binary trees in Python I’ve been playing around with sequentially represented binary trees recently, i.e. a binary tree given as a list of integers where the node values are in contiguous sections of the list. For example, a binary tree where the node values are also their indexes would be sequentially represented like this: 0 | 1, 2 | 3, 4, 5, 6 | 7, 8, 9, 10, 11, 12, 13, 14 Each section in the list represents o
