Enumerators in python & How they work? ..

[Humble]

Enumerators in python is very helpful and give “index” access to your iteratable object..

The input for your enumerator should be an iterator .. Please watch below example.

>>>> l=[10,3,4,5,6]
>>> for i,j in enumerate(l):
...      print "%s is in index %s" %(j,i)
... 
10 is in index 0
3 is in index 1
4 is in index 2
5 is in index 3
6 is in index 4
>>> 

>>>

If you would like to fetch specific index , here is an example:

>>>> for i,j in enumerate(l):
...     if j==1:
...             print "%s is at index:%s" %(j,i)
... 
1 is at index:0
1 is at index:5
>>>
