　　直接见代码：

 1 #!/usr/bin/env python

 6 def add(x=0, y=1):
 7     """
 8     add input args x and y.
 9     :param x:
10     :param y:
11     :return: x + y
12     """
13     return x + y
14 
15 
16 if __name__ == ‘__main__‘:
17     print dir(add)
18     attr_name_list = [
19         ‘func_closure‘, ‘func_code‘,
20         ‘func_defaults‘, ‘func_dict‘,
21         ‘func_doc‘, ‘func_globals‘,
22         ‘func_name‘
23     ]
24     for attr_name in attr_name_list:
25         print attr_name.ljust(15), ‘:‘, getattr(add, attr_name)
26     print ‘func_code_filename: ‘, add.func_code.co_filename

 

结果如下：获取函数名称和文件位置：func_name, func_code.co_filename。
