Python Basics : Lesson 6 : Strings in Python 3 [ for dummies ]

A string in computing is a finite sequence of characters that could be from an alphabet of a set. Strings in Python are variables where as some programming languages support constant strings as well.

The two basic functions strings support is the concatenation and sub-strings. Concatenation is about the joining two strings using the '+' (plus) operation. Sub string is the extraction of a string contained within a larger string, hence a sub-string.

Other than that strings in Python support many inbuilt functions and this video tutorial uses few of them.
