Generator comprehensions

You are given the following generator functions (you can test them in the console):

def func1(n):
  for i in range(0, n):
    yield i**2

def func2(n):
  for i in range(0, n):
     if i%2 == 0:
       yield 2*i

def func3(n, m):
  for i in func1(n):
    for j in func2(m):
      yield ((i, j), i + j)

Note that func3() uses internally func1() and func2().
