iter Function in Python Syntax

The iter() method in Python has the following syntax:

Syntax : iter(obj, sentinel)

Parameters : 

• obj : Object which has to be converted to iterable ( usually an iterator ).
• sentinel : value used to represent end of sequence.

Returns : Iterator object

Properties of Iterators

• The iteration object remembers the iteration count via the internal count variable.
• Once the iteration is complete, it raises a StopIteration exception and the iteration count cannot be reassigned to 0.
• Therefore, it can be used to traverse the container just once.

python iter() method returns the iterator object, it is used to convert an iterable to the iterator.
