<h2 id="orgheadline1">getfile函数</h2>
<div class="outline-text-2" id="text-1">
<p>
传入python object，返回定义该object具体是在那个文件中的。可以如下获取该文件的系统绝对路径地址:
</p>
<pre>
os.path.abspath(inspect.getfile(func))
</pre>

<p>
值得一提的是，如果该模块被安装进入系统了，那么实际该文件的地址应该是类似这样的形式:
</p>
<pre>
/usr/local/lib/python3.4/dist-packages/infome-15.10.30-py3.4.egg/infome/web/youdao.py
</pre>

<p>
注意该egg的名字后面的版本号。

<div class="outline-2">
<h2 id="orgheadline2">getcallargs函数</h2>
<div class="outline-text-2" id="text-2">
<p>
如下所示:
</p>
<pre>
params = inspect.getcallargs(func,*args,**kargs)
</pre>
<p>
相当于模拟执行了func函数，然后返回如果执行func函数时其接受的参数字典值（包括必填参数和可选参数）。
