我想找到我的硒文本字段，但我不知道该怎么做的正是（我用的第一次硒）。
我尝试了以下选项来尝试，但没有奏效
driver.find_element_by_name(Token).send_keys(abcdefghijklm)driver.find_element_by_class_name('form-control.ng-untouched.ng-pristine.ng-valid').send_keys("asbfsbgkf")driver.find_element_by_cssSelector("input.form-control ng-untouched ng-pristine ng-valid[placeholder='Token string']")driver.findElementByCSSSelector("input.form-control ng-untouched ng-pristine ng-valid[placeholder='Token string']")driver.find_element_by_xpath("//input[@class='form-control ng-untouched ng-pristine ng-valid'][@type='text']").send_keys("asbfsbgkf")有人，请帮我在这里。我真的很感激。
下面是HTML：（突出了一个我需要搜索 - “二值”输入）

second_input_xpath = "//div[@class='input-group-mt-2'][2]//input"
driver.find_element_by_xpath(second_input_xpath ).send_keys("asbfsbgkf")
关于主要错误在标题看起来你没有正确初始化自己的Chrome的webdriver。我建议在硒文档看here。
貌似为了使其独特尝试这种具有相同的类name.So所有输入字段。
driver.find_element_by_xpath("(//input[@class='form-control ng-untouched ng-pristine ng-valid'])[n]").send_keys("value")
where n=1,2,3...n
PS N = 1为第一element.Kindly让我知道，如果这有助于。
