Hallo, everyone

I am new to Mathematica, and I get one problem now, hope to get some
help here

I got a list like this:

{{0, 0, 0, 0, 0, 0, 0, 0, 0, 0}, {0, 1, 1, 0, 0, 0, 1, 0, 0, 0},
{0, 0, 0, 0, 1, 1, 0, 0, 2, 0}, {1, 0, 1, 0, 0, 1, 0, 1, 0, 0},
{1, 3, 3, 4, 2, 2, 5, 3, 2, 1}, {7, 2, 2, 3, 4, 4, 0, 3, 1, 3}}

I need to get a list to show the number of non zero number in each sub
list, as to say, I need to get a list like this:

{0,3,3,4,10,9}

Thanks alot!
