Indexing in Python refers to the position of elements in an iterable object like a string. Index positions start from 0, so the first element is at index 0. For a string like "Hello", its elements can be accessed using square brackets and specifying the index number, like print(message[1]) to print the letter "e", which is at index 1. Indexing allows programmatically accessing and manipulating individual elements in an iterable object.

What is index?
>>>Index in Python refers to
the position of an “Iterable”.
>>>Index position starts from
the position ZERO ‘0’

EXAMPLE:
Let’s take this string: “Hello”
>>>Index Positioning works like:
“|H|e|l|l|o|”

4. “Indexing”
XIndexing
EXAMPLE:
“|H|e|l|l|o|”
>>>The slices represents an
index position, and it starts
from Index Position ZERO

XIndexing
EXAMPLE:
“|H|e|l|l|o|”
>>>You can call an Index
Position and get the value it
holds using Square Brackets []

6. “Indexing”
XIndexing
EXAMPLE:
“|H|e|l|l|o|”
>>>To call the letter “e”, just
refer to the index position 1,
since indexing starts from ZERO

7. “Indexing”
XIndexing
EXAMPLE:
message = “|H|e|l|l|o|”
>>>That’s why you can print the
“e” by typing: print(message[1])
