@Venkatesh Pitta is right: extend() method add all items of the passed list/tupple to the targeted list, while append() method will add a list/tupple as only once new item ^^ list = [1,2,3] list.append(4) # list is now [1,2,3,4] list.append([5,6]) # list is now [1,2,3,4,[5,6]] list.extend([7,8,9]) # list is now [1,2,3,4,[5,6],7,8,9] Anyway, you can simply use list concatenation operator '+'... list = [1,2,3] list = list + [4,5,6] # list is now [1,2,3,4,5,6] # or shortener: list += [7,8,9] # list is now [1,2,3,4,5,6,7,8,9]

look into extend method on lists. example: l = [] l.extend((1,2,3,4)) print(l) ## [1, 2, 3, 4] is the output.

The append method only takes a single argument. In order to add multiple values at once, you'll have to append a list of values. example: list_1 = [] list_1.append([1,2,3])
