Is there any difference — performance or otherwise — between generator expressions and generator functions?
In [1]: def f():
...: yield from range(4)
...:
In [2]: def g():
...: return (i for i in range(4))
...:
In [3]: f()
Out[3]: <generator object f at 0x109902550>
In [4]: list(f())
Out[4]: [0, 1, 2, 3]
In [5]: list(g())
Out[5]: [0, 1, 2, 3]
In [6]: g()
Out[6]: <generator object <genexpr> at 0x1099056e0>
