Description: # Intro to Python Python is a simple, easy-to-learn, pseudo-code resembling programming language. It is rich with all the features of any object oriented language. Scientists and Mathematicians have been using python since its inception and hence is popular for analytical tasks. Python is also known for its brevity.  ## Why is Python a Favorite of Data Scientists?

SQL in Python. Continue

Description: # SQL in Python. As mentioned in earlier lessons, Python is very flexible and has a wide range of libraries and third-party modules to support many operations. SQL (Structured Query Language) can be executed from within Python using sqlite3. The sqlite3 module offers support to connect to an external database and execute SQL queries. However, this module does not offer the complete querying capability of a typical SQL engine and functions as a light-weight API version of the querying engine. Other modules like MySQLdb (same as mysql-python), offer a more extensive range of functions and query processing abilities. We will be discussing sqlite3 module, as it is the widely used. Though it is a light-weight module, it supports almost all basic sql operations and can be implemented for a database of up to 140 Terabytes in size.

Description: # Introduction to Statistics ## Mean, Median and Mode When working with a large data set, it can be useful to represent the entire data set with a single value that describes the "middle" or "average" value of the entire set. In statistics, that single value is called the central tendency and mean, median and mode are all ways to describe it.

Description: # Numpy ## Arrays and Lists Before getting introduced to Numpy library, we need to be familiar with a very widely used data structure called 'array'. An array is a collection of homogenous variables. Here homogenous means variables of the same data type. And so an array can be a collection of integers (int datatypes), collection of fractions/decimal values (float datatypes) or a collection of characters (char datatype) also referred to as a string.
