既然class也是object,那么我们就可以像创建普通的object一样动态创建class。 第一种方法,我们可以在方法中创建class。如下面的例子所示: >>>defdynamic_class_creater(name):...if name=='name1':...classclass1(object):... pass...return class1...else:...classclass2(object):... pass...return cla...

Python 标准库自带了强大的 logging 日志模块,在各种 python 模块中得到广泛应用。 一、简单使用 1. 入门小案例 importlogging # 默认的warning级别,只输出warning以上的 # 使用basicConfig()来指定日志级别和相关信息 logging.basicConfig(level=logging.DEBUG,# 设置级别,根据等级显示 ...
Class variables are defined within theclass construction. Because they are owned by the class itself, class variables are shared by all instances of the class. They therefore will generally have the same value for every instance unless you are using the class variable to initialize a variable. ...
