By: Karthik Janar : 2018-04-12

Description: In the world of data science, two popular programming languages are used today. R and Python. For a good comparison of R and Python read this tutorial. Personally I prefer R over Python because of its rich set of freely available packages and its visualization capabilities. R is based on an older language named S. S was originally developed at Bell Labs by John Chambers in 1976 as an internal statistical analysis environment using fortran libraries. In 1988 it was rewritten in C.

By: Ashley J : 2017-09-28

Description: An item in a dictionary is a key/value pair. You can think of a dictionary as an associative array (known in some other languages as an “unordered map,” “hash table,” or “hash”). Keys in a dictionary may be of different types, but they must be hashable. Values in a dictionary are arbitrary objects and may be of any type.


9. python list

By: Ashley J : 2017-09-27

Description: A Python list is a mutable ordered sequence of items. The items of a list are arbitrary objects and may be of different types. To denote a list, use a series of expressions (the items of the list) separated by commas (,), within square brackets ([]); if every item is a literal, the whole assembly is a list literal. You may optionally place a redundant comma after the last item. To denote an empty list, use an empty pair of brackets


10. python string

By: Ashley J : 2017-09-27

Description: Python String objects (byte strings, as well as text, AKA Unicode, ones) are immutable: attempting to rebind or delete an item or slice of a string will raise an exception. The items of a string object (corresponding to each of the characters in the string) are themselves strings of the same kind, each of length 1.
