I have lists of data such as
a = [1,2,3,4]
b = ["a","b","c","d","e"]
c = ["001","002","003"]
And I want to create new another list that was mixed from all possible case of a,b,c like this
d = ["1a001","1a002","1a003",...,"4e003"]
Is there any module or method to generate d without write many for loop?
