Title

I am trying to flatten a list using list comprehension in python. My list is somewhat like [[1, 2, 3], [4, 5, 6], 7, 8] just for printing then individual item in this list of list I wrote this function: def flat(listoflist): for item in listoflist: if type(item) != list: print(item) else: for num in item: print(num) interactive output: >>> flat(list1) 1 2 3 4 5 6 7 8 Then I used the same logic to flatten my list through list comprehension I am getting the following error list2 = [item if type(item) != list else num for num in item for item in list1] Which gives me the following error: Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: 'int' object is not iterable How can I flatten this type of list-of-list using using list comprehension ?
