Python硒不适用于WebDriverWait - python

我尝试使用硒登录google。如果我像这样的代码使用sleep（）就可以了

browser = webdriver.Firefox()
browser.get('https://admin.google.com/')

emailElem = browser.find_element_by_id('Email')
emailElem.send_keys('mymail')
nextButton = browser.find_element_by_id('next')
nextButton.click()

sleep(5)
passwordElem = browser.find_element_by_id('Passwd')
passwordElem.send_keys('mypass')
signinButton = browser.find_element_by_id('signIn')
signinButton.click()

如果我像这样将睡眠更改为WebDriverWait

browser = webdriver.Firefox()
browser.get('https://admin.google.com/')

emailElem = browser.find_element_by_id('Email')
emailElem.send_keys('mymail')
nextButton = browser.find_element_by_id('next')
nextButton.click()


passwordElem = WebDriverWait(browser, 5).until(
    EC.presence_of_element_located(browser.find_element_by_id('Passwd'))
)
passwordElem.send_keys('mypass')
signinButton = browser.find_element_by_id('signIn')
signinButton.click()

它显示这样的错误。

selenium.common.exceptions.NoSuchElementException: Message: Unable to locate element: [id="Passwd"]

如何使用WebDriverWait？

参考方案

是的，正如Guy所说，您browser.find_element_by_id('Passwd'))不是必需的。如documentation所示，更改为((By.ID, "Passwd")))。代码如下：

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait 
from selenium.webdriver.support import expected_conditions as EC 

browser = webdriver.Firefox()
browser.get('https://admin.google.com/')

emailElem = browser.find_element_by_id('[email protected]')
emailElem.send_keys('youremail')
nextButton = browser.find_element_by_id('next')
nextButton.click()


passwordElem = WebDriverWait(browser,     5).until(EC.presence_of_element_located((By.ID, "Passwd")))

passwordElem.send_keys('yourpassword')
signinButton = browser.find_element_by_id('signIn')
signinButton.click()

R'relaimpo'软件包的Python端口 - python

我需要计算Lindeman-Merenda-Gold（LMG）分数，以进行回归分析。我发现R语言的relaimpo包下有该文件。不幸的是，我对R没有任何经验。我检查了互联网，但找不到。这个程序包有python端口吗？如果不存在，是否可以通过python使用该包？ python参考方案 最近，我遇到了pingouin库。
