I have added a new application of the iter() function. I have shown how we can check if an object in python is iterable or not.

+## Checking if object is iterable or not
+
+There is an easy way of checking if an object in python is iterable or not. The following code will do the needful.
+```python
+>>> def check(A):
+...     try:
+...         st = iter(A)
+...         print('yes')
+...     except:
+...         print('no')
+...
+>>> check(25)
+no
+>>> check([25,35])
+yes
+>>>
+```
+Here you can observe that the 25 is an integer, so it is not iterable, but [25,35] is a list which is iterable so it outputs no and yes respectively.
