    [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:

    [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

    s = Student.Student()
