Python瓶运行初始化方法两次

Question

我有瓶子问题,_initialize功能运行两次.应用示例:

 @route("/index")
 def index():
      return "bang"

 def _initialize():
      print("bam")

 if __name__ == "__main__":
     _initialize()
     run(reloader=True, host="localhost", port = 8990)

输出是:

bam
bam
Bottle v0.11.rc1 server starting up (using WSGIRefServer())...                             
Listening on http://localhost:8080/                                                        
Hit Ctrl-C to quit.

为什么会这样？我怎么能在瓶子里做这样的pre init？

问题是函数的reloader=True论证run.请参阅http://bottlepy.org/docs/dev/tutorial.html#auto-reloading中的句子:

所有模块级代码至少执行两次!小心.
