Nested Generators

Hi guys,
I recently tried to nest a generator in a generator, similar to this

def Nested_Generator():
    x = (i for i in range(10))
    y = (i*x[i] for i in range(10))
    yield y

I discovered this doesn't work. I'm using python 3.6. How do you get around this?

My actually application is performing a list comprehension on a BeautifulSoup.findAll object. In order to format the data correctly I need to perform multiple list comprehensions. The resulting one I intend to write to an SQLlite database. The lists are getting out of hand... as you might expect.
