find_element_by_xpath()to发生了变化find_element(By.Xpath)，现在点击不起作用。

代码试验：

search_btn = self.driver.find_elements(
    By.XPATH, "//*[@id='viewContainer']/app-listing-container/app-search-container/app-search-form-container/form/div[3]/button[2]").click()
time.sleep(4)
search_btn.click()
time.sleep(5)

错误：

查找元素（）

find_elements()查找元素并返回一个列表，给定一个By策略和定位器。

所以这行代码：

search_btn = self.driver.find_elements( By.XPATH, "//[@id='viewContainer']/app-listing-container/app-search-container/app-search-form-container/form/div[3]/button[2]")

将返回一个列表，并且列表没有click()方法。因此下一行：

search_btn.click()

引发错误：

AttributeError: 'list' object has no attribute 'click'

解决方案

将find_elements()替换为find_element()就可以了。
