Python iter() Function

The iter() method in Python creates an iterator from an iterable, allowing us to traverse a collection one element at a time. Here's a simple example to understand how it works.

iter(object, sentinel)

• Object - Required. An iterable Object
• sentinel - Optional. The sentinel value is a special value that stores the end of the sequence.

# Define a list
my_list = [1, 2, 3, 4]

# Create an iterator from the list
my_iterator = iter(my_list)

# Use the iterator to traverse through the list
print(next(my_iterator)) 
print(next(my_iterator))  
print(next(my_iterator))  
print(next(my_iterator))
