PS:Python中的变量,引用等设计和其他语言不同,这里只是将原文翻译说明了一下,更多的介绍可以参看: Python中的变量、引用、拷贝和作用域 十三、Python方法中参数的默认值(Default Parameter Values) 对于Python初学者来说,Python的方法默认参数有一个很容易犯错的地方:在默认参数中使用可变对象,甚至有不少Python老鸟也可...

Next, define a class where you decorate some of its methods using the @debug and @timer decorators from earlier:Python class_decorators.py from decorators import debug, timer class TimeWaster: @debug def __init__(self, max_num): self.max_num = max_num @timer def waste_time(self, ...

Define each parameter in the script. When you define a parameter, you are specifying whether each parameter in the general script is an input or output parameter, and the type of data that it requires. To do so: At the bottom of the page, select Parameters. The Par...
和optpars中的参数类型类似是通过参数 “type=xxx” 定义的,tf中每个合法类型都有对应的 “DEFINE_xxx”函数。常用: tf.app.flags.DEFINE_string() :定义一个用于接收string类型数值的变量; tf.app.flags.DEFINE_integer() : 定义一个用于接收int类型数值的变量; tf.app.flags.DEFINE_float() : 定义一个用于...
