method是EC即expected_conditions类提供的预先判断条件如下: WebDriverWait(driver,10).until(EC.title_is(u"百度一下,你就知道")) # 判断title,返回布尔值 WebDriverWait(driver,10).until(EC.title_contains(u"百度一下")) # 判断title,返回布尔值 WebDriverWait(driver,10).until(EC.presence_of_element_loc...
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...
Explicit 在上面的例子中体现在哪呢? 我理解它的重点在于,当所有的if语句都不命中时,默认的行为是未知的,而显示写出的return None则清楚地描述了默认的情形,即使 Python 的默认行为发生变化,该方法的行为也不会发生变化。 要具体、要特化 这篇文章 明确表达了自己对“Explicit is Better than Implicit”的理解: B...

import this | 《Python的禅》,Tim Peters著美丽胜于丑陋。显式比隐式好。简单总比复杂好。复杂总比隐晦好扁平比嵌套好。稀疏胜于稠密。可读性很重要。特殊情况不足以打破规则。尽管实用胜过纯粹。错误永远不应该悄无声息地过去。除非明确沉默。面对歧义,拒绝猜测的诱惑。应该有一种——最好只有一种——显而易见...

Some tests make use of implicit relative imports (e.g. import fauxdbi) which don't work in all environments. Using explicit relative imports (e.g. from . import fauxdbi) makes it easier to use the package and run the test suite in more environments....
Implicit conversion in computer science refers to the automatic conversion of one data type to another by the compiler without requiring any explicit instructions from the programmer. AI generated definition based on: API Design for C++, 2011 ...
“Explicit is better than implicit” 是 The Zen of Python 中的一句格言。长久以来都觉得挺在理,直到有天有人用这句话为基础,提出了一个我不甚赞同的观点,才发现从来就没有真正理解过它。 神奇的是在搜索过程中,发现讨论这句格言的并没有多少,不同的讨论中对 "explicit" 含义的理解差别也很大,最终发现最...
