Indexing
Each individual character in a string can be accessed using a technique called indexing .
- The index specifies the character to be accessed in the string and is written in square brackets ([ ]).
- The index of the f irst character (from left) in the string is 0 and the last character is n-1 where n is the length of the string.
- If we give an index value out of this range then we get an IndexError.
- The index must be an integer (positive, zero or negative) .
