python模块导入

[seemmo@RegionServer1 duwen]$ python Python 2.6.6 (r266:84292, Nov 22 2013, 12:16:22) [GCC 4.4.7 20120313 (Red Hat 4.4.7-4)] on linux2 Type "help", "copyright", "credits" or "license" for more information.

   import Student
 s = Student()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'module' object is not callable
 from  Student  import *
 s = Student() 

原因：

import module 和 from module import，区别是前者所有导入的东西使用时需加上模块名的限定，而后者不要。

可以试试：

TypeError: 'module' object is not callable
 s = Student.Student()
