Take first Elements of sublists - quest - Apr-26-2021 This is my list: list_of_lists = [[1, 2], [3, 4]]I want to group of elements of sublists: list_of_lists = [[1, 2], [3, 4]] n=[] for list in list_of_lists: n.append(list[0]) #I am taking 1 and 3 n.append(list[1]) # I am taking 2 and 4But sometimes I can have 100 elements too so I want to do it dynamically instead of writing [0],[1] How can I do that? RE: Take first Elements of sublists - perfringo - Apr-26-2021 Have a look at built-in zip RE: Take first Elements of sublists - buran - Apr-26-2021 list_of_lists = [[1, 2], [3, 4]] print(list(zip(*list_of_lists)))
