python类中的声明等同于_init_？

Question

我想知道放在python类顶部的声明是否等同于语句__init__？例如

import sys

class bla():
    print 'not init'
    def __init__(self):
        print 'init'
    def whatever(self):
        print 'whatever'

def main():
    b=bla()
    b.whatever()
    return 0

if __name__ == '__main__':
    sys.exit( main() )

输出是:

not init
init
whatever

作为旁注,我现在也得到:

Fatal Python error: PyImport_GetModuleDict: no module dictionary!

有关为什么会这样的想法？先感谢您!

不,这不等同.即使在实例化类型对象之前,也会在定义print 'not init'类时运行该语句.blabla

>>> class bla():
...    print 'not init'
...    def __init__(self):
...        print 'init'
not init

>>> b = bla()
init
