Not valid:

(l for l in ls if l[2] == False for ls in lss)

Valid:

(l for ls in lss for l in ls if l[2] == False)

I guess the order of the fors mimcs the order in a nested for loop, but then something like

(for ls in lss for l in ls if l[2] == False: l)

would be even closer.

Deleting a if statement whose condition is never true can convert a generator into a normal function.

def g():
    if False: yield "Hello"
    pass

def h():
    pass
