Hello @Manan_Jain
None is a keyword in Python to define Null objects or variables. In this case, we have created a list new_list of length length and initialized all values to None. For instance, if the length of the list was 3, then the new_list will be [None, None, None]. This syntax of multiplying is just a way in Python to initialize a list of certain length with some default values.
Hope this helps!
