隐式等待(implicit) 隐式等待是设置全局的查找页面元素的等待时间,在这个时间内没找到指定元素则抛出异常,只需设置一次,语法如下: driver.implicitly_wait(time) 显示等待(explicit) 显式等待是使用频率最高的获取页面元素超时设置,其原理是通过设置一个最大时间和一个周期时间,按照周期时间来检测是否出现等待元素,直到...
隐式等待(implicit)隐式等待是一种设置全局查找页面元素等待时间的方法。在此等待时间内,如果未找到指定元素,则会抛出异常。设置隐式等待只需一次,其语法如下:显示等待(explicit)显式等待是获取页面元素超时设置中使用频率最高的方法。其原理是通过设置最大等待时间和周期时间,按照周期时间检测是否出现等...
我们通过reveal_type得知,mypy将arg的类型推导为Optional[str]。这个推导本身没有错,但是,考虑到zen of python的要求, explicit is better than implicit,我们应该将arg的类型声明为arg: Optional[str]。从0.980起,mypy默认将implicit_optional设置为Flase(即禁止这样使用),因此,这个选项也没有出现在我们的示例中。 4...
这篇文章 明确表达了自己对“Explicit is Better than Implicit”的理解: Being explicit means being concrete and specific instead of abstract and general. It also means not to hide the behavior of a function. Explicit 意味着要具体、特化,不要抽象、通用。同时不要隐藏函数的行为。 对于要具体、特化,文...
