Python enumerate() Function | Enumerate function Python
Enumerate is a built-in function in python that allows you to keep track of the number of iterations (loops) in a loop. This enumerate object contains a count (from the start, which always defaults to 0) and a value obtained from iterating over the iterable object.

Python Notes:
Enumerate in python
The enumerate() function adds a counter to an iterable and returns it (the enumerate object).

The enumerate() function is a built-in function that returns an enumerate object. This lets you get the index of an element while iterating over a list.

In other programming languages (C), you often use a for loop to get the index, where you use the length of the array and then get the index using that. That is not Pythonic, instead you should use enumerate().

In Python you can iterate over the list while getting the index and value immediately.

The basic syntax is is enumerate(sequence, start=0)

The enumerate() function takes two arguments:

iterable - a sequence, an iterator, or objects that support iteration
start (optional) - enumerate() starts counting from this number. If start is omitted, 0 is taken as start.
