List derivation

Of all the bizarre grammars, list deductions should be used the most frequently, and the simplification of the code is also obvious. For example, to find the square of each element of a list, you should usually write like this (of course, there are other ways to write it, such as using the map function):

> a = [1,2,3,4,5] > > result = list () > for i in a:result.append (iTuni) > result [1,4,9,16,25]
