 ### Snippet submission and Pull request guidelines
@@ -24,7 +24,7 @@ Here's what you can do to help:
 - **Snippets _CAN NOT_ use any external modules**. Only the modules and function inbuilt in `python 3.6` shall be used.
 - **Snippet code** must be enclosed inside ` ```python ` and ` ``` `.
   - Remember to start your snippet's code on a new line below the opening backticks.
-  - Please follow [This Style Guide](https://www.python.org/dev/peps/pep-0008/) for your code.
+  - Please follow [This Style Guide](https://www.python.org/dev/peps/pep-0008/) for your code.(Though it doen't matter much as your code is automatically prettified)
   - Try to keep your snippets' code short and to the point. Use modern techniques and features. Make sure to test your code before submitting.
   - All snippets must be followed by one (more if necessary) test case after the code, in a new block enclosed inside ` ```python ` and ` ``` `. The syntax for this is `myFunction('testInput') # 'testOutput'`. Use multiline examples only if necessary.
   - Try to make your function name unique, so that it does not conflict with existing snippets.

+### chunk 
+
+Chunks an array into smaller arrays of a specified size.
+
+Uses `range` to create a list of desired size. Then use `map` on this list and fill it with splices of `arr`
+
+```python 
+from math import ceil
+
+
+def chunk(arr, size):
+    return list(
+        map(lambda x: arr[x * size:x * size + size],
+            list(range(0, ceil(len(arr) / size)))))
+
+```
+
+``` python
+    chunk([1,2,3,4,5],2) # [[1,2],[3,4],5]
+```
 ### gcd
 
 Calculates the greatest common divisor between two or more numbers/arrays.
