<p>我想你在找<a href="http://docs.python.org/2/library/itertools.html#itertools.chain.from_iterable" rel="nofollow">itertools.chain.from_iterable</a>：</p>
<pre><code>import os
import glob
import itertools
for each in itertools.chain.from_iterable(
glob.glob(os.path.join(eachDir,'/*.h'))
for eachDir in subDirs):
print each
</code></pre>
<hr/>
<p>它压平了一堆难以忍受的东西：</p>
<pre><code>In [6]: import itertools as IT
In [7]: list(IT.chain.from_iterable([['a', 'b', 'c'], [1, 2, 3]]))
Out[7]: ['a', 'b', 'c', 1, 2, 3]
</code></pre>
