How to create and fill a list of lists in a for loop

Question

I\'m trying to populate a list with a for loop. This is what I have so far:

newlist = []
for x in range(10):
    for y in range(10):
        newlist.append(y         


        

Answer 1

Alternatively, you only need one loop and append range(10).

newlist = []
for x in range(10):
    newlist.append(list(range(10)))

Or

newlist = [list(range(10)) for _ in range(10)]
