Python next() Function

In this guide, we are going to show you what is python next() function and how to use them to find the next item of an iterable.
To understand this example, you should have basic knowledge of the Python iter() function to get the iter object.

Python next function

Python next function is a built-in function that is used to find the next item of an iterable. You can add a default value, to return if the iterable reached the end.

Syntax

The syntax of next function in Python is:-

next(iterable, default)

Parameters

next function in Python accepts two parameters.

• iterable:- Required, An iterable object
• default:- Optional. A default value if the iterable reached the end.

Return Value

The return value of next function in Python is next item of iterable.

Python next example

Here we will see some example to understand next function in Python.

Example 1:

#List iterable
my_iterable = ['Python', 'C#', 'Java', 'PHP', 'Ruby']

#Create iterator object.
iter_object = iter(my_iterable)

print(next(iter_object))
print(next(iter_object))
print(next(iter_object))
print(next(iter_object))
print(next(iter_object))

Output

Python
C#
Java
PHP
Ruby

Example 2:

#List iterable
my_iterable = ['Python', 'C#', 'Java', 'PHP', 'Ruby']

#Create iterator object.
iter_object = iter(my_iterable)

for i in range(len(my_iterable)):
	print(next(iter_object))

Output

Python
C#
Java
PHP
Ruby

Example 3:

Here we will use next function with default value.

#List iterable
my_iterable = ['Python', 'C#', 'Java', 'PHP', 'Ruby']

#Create iterator object.
iter_object = iter(my_iterable)

for i in range(len(my_iterable) + 1):
	print(next(iter_object, 'HTML'))

output

Python
C#
Java
PHP
Ruby
HTML
