Counting How Many Times There Are Blank Lists In A List Of List

I have a list: l = [['a', []], ['b', []], ['c', []], ['d', ['e']], ['f', []], ['g', ['h']], ['i', ['j']]] I want to count how many lists have the element [] next to the first elem

Solution 1:

Here is a single line solution doing what you want

defcounting(l):
    returnsum(x.count([]) for x in l)

Solution 2:

Since you require the empty list to be after the first element in each list this would work. Updated.

sum([1 for x in l if x[1]==[]])
