First of all, I think it is not necessary to understand or learn a concept if it is not understood or affected. Closure is such a concept that you can use well without understanding it. I have been writing as3 programs in the past two years. I have been dealing with as3 programs every day. I have even had one function set, and one method has more than 20 function extreme examples, but we never know how it works. it's just like water and air. we don't need it.

List data types and common operations of python, and list data types of python A list is the most common Python data type. It can appear as a comma-separated value in square brackets. Each element in the list is assigned a number-its location, or index. The first index is 0, the second index is 1, and so on. Operations that can be performed on the list include indexing, slicing, adding, multiplication, and checking members. In addition, Python has built-in methods to determine the sequence lengt
