英文:
Does WebElement class inherits from WebDriver class in Selenium Python?
问题
在代码的第二行，我使用了Webdriver类的find_element_by_xpath()方法与WebElement对象，它运行正常。
这是如何实现的呢？在Selenium Python中，WebElement类是否继承自WebDriver类？
Selenium Python中的WebElement类并没有继承自WebDriver类。那么，我们如何能够在WebElement对象中使用WebDriver类的方法呢？
英文:
Sample code:
score_both_halves = driver.find_element_by_xpath('//label[@data-btn-radio="\'ScoreBothHalves\'"]')
score_both_halves.find_element_by_xpath()
In the second line of code I used a find_element_by_xpath() method of Webdriver class with WebElement object and it works fine.
How is that possible? Is WebElement class inherits from WebDriver class in selenium python?
Isn't the WebElement class inherits from WebDriver class in selenium python? If not then how we can use methods of WebDriver class with WebElement object?

得分: 1
-
Remote WebDriver实现包含方法find_element()
-
用法：
element = driver.find_element(By.ID, 'foo') -
返回类型：
WebElement
-
-
同样，Remote WebElement实现也包括方法find_element()
-
用法：
element = element.find_element(By.ID, 'foo') -
返回类型：
WebElement
-
结论
因此，driver.find_element(By.ID, 'foo') 和 element.find_element(By.ID, 'foo') 都是有效的代码行。
英文:
As per the Selenium Python binding documentation:
-
The Remote WebDriver implementation contains the method find_element()
-
Usage:
element = driver.find_element(By.ID, 'foo') -
Return type:
WebElement
-
-
Similarly The Remote WebElement implementation also includes the method find_element()
-
Usage:
element = element.find_element(By.ID, 'foo') -
Return type:
WebElement
-
Conclusion
Hence driver.find_element(By.ID, 'foo') and element.find_element(By.ID, 'foo') both are valid lies of code.
