The Python function iter is utilized to generate an iterator object. This function constructs an object that allows for iteration over its elements sequentially, one at a time.
Python iter Function Syntax
It has the following syntax:
Example
iter(object, sentinel)
Parameters
- object: An iterable object.
- sentinel (optional): It is a special value that represents the end of a sequence.
Return
It returns an iterator object.
Python iter Function Example
The example provided below demonstrates how the iter function operates within Python.
Example
# list of numbers
list = [1,2,3,4,5]
listIter = iter(list)
# prints '1'
print(next(listIter))
# prints '2'
print(next(listIter))
# prints '3'
print(next(listIter))
# prints '4'
print(next(listIter))
# prints '5'
print(next(listIter))
Output:
Output
1
2
3
4
5
Explanation:
In the example provided, the iter function transforms a list iterable into an iterator.
