5-2中,python3没有readinto方法

Question

视频中是这样的，

buf = array.array('h', (0 for _ in range(n)))
f.readinto(buf)

然后我用这种方法解决了，请问有更好的方法吗？

buf = array.array('h', [])
buf.frombytes(f.read())

array.fromfile(f, n)

Read n items (as machine values) from the file object f and append them to the end of the array.  If less than n items are available,EOFError is raised, but the items that were available are still inserted into the array. f must be a real built-in file object; something else with a read() method won’t do.
