# Break a list into chunks of size N in Python

Method 1: Using yield
The yield keyword enables a function to comeback where it left off when it is called again. This is the critical difference from a regular function. A regular function cannot comes back where it left off. The yield keyword helps a function to remember its state. The yield enables a function to suspend and resume while it turns in a value at the time of the suspension of the execution.

 `my_list ``=` `[``'geeks'``, ``'for'``, ``'geeks'``, ``'like'``, ` `           ``'geeky'``,``'nerdy'``, ``'geek'``, ``'love'``, ` `               ``'questions'``,``'words'``, ``'life'``] ` ` `  `# Yield successive n-sized ` `# chunks from l. ` `def` `divide_chunks(l, n): ` `     `  `    ``# looping till length l ` `    ``for` `i ``in` `range``(``0``, ``len``(l), n):  ` `        ``yield` `l[i:i ``+` `n] ` ` `  `# How many elements each ` `# list should have ` `n ``=` `5` ` `  `x ``=` `list``(divide_chunks(my_list, n)) ` `print` `(x) `

Output:

```[['geeks', 'for', 'geeks', 'like', 'geeky'],
['nerdy', 'geek', 'love', 'questions', 'words'],
['life']]
```

Method 2: Using List comprehension
List comprehension is an elegant way to break a list in one line of code.

 `my_list ``=` `[``1``, ``2``, ``3``, ``4``, ``5``, ` `              ``6``, ``7``, ``8``, ``9``] ` ` `  `# How many elements each ` `# list should have ` `n ``=` `4`  ` `  `# using list comprehension ` `final ``=` `[my_list[i ``*` `n:(i ``+` `1``) ``*` `n] ``for` `i ``in` `range``((``len``(my_list) ``+` `n ``-` `1``) ``/``/` `n )]  ` `print` `(final) `

Output:

```[[1, 2, 3, 4], [5, 6, 7, 8], ]
```

Alternate Implementation :

 `l ``=` `[``1``, ``2``, ``3``, ``4``, ``5``, ``6``, ``7``, ``8``, ``9``]  ` `  `  `# How many elements each  ` `# list should have  ` `n ``=` `4` `  `  `# using list comprehension  ` `x ``=` `[l[i:i ``+` `n] ``for` `i ``in` `range``(``0``, ``len``(l), n)]  ` `print``(x) `

Output:

```[[1, 2, 3, 4], [5, 6, 7, 8], ]
```
