 #### Other Standard While Submitting Your Work
 
-- File extension for code should be `.py`.
-
-- Please file your work to let others use it in the future. Here are the examples that are acceptable:
+- File extension for code should be `.py`. Jupiter notebook files are acceptable in machine learning algorithms.
 
-  - Camel cases
-  - `-` Hyphenated names
-  - `_` Underscore-separated names
+- Strictly use snake case (underscore separated) in your file name, as it will be easy to parse in future using scripts.
 
   If possible, follow the standard *within* the folder you are submitting to.
