Selenium Python中的元素识别问题

Question

Here is my current code:

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

driver = webdriver.Chrome(executable_path= "C:\Drivers\chromedriver")
driver.get("https://www.expedia.com/")
driver.maximize_window()
driver.implicitly_wait(5)

driver.find_element(By.XPATH, "//*[@id='uitk-tabs-button-container']/li[2]/a/span").click()
time.sleep(15)
driver.find_element(By.ID, "location-field-leg1-origin-dialog-trigger").send_keys("BLR")
driver.find_element(By.ID, "location-field-leg1-destination-dialog-trigger").send_keys("BOM")
driver.find_element(By.ID, "departure").send_keys("Fri Nov 06 2020")
driver.find_element(By.XPATH, "//*[@id='root']/div/div[2]/div/div/div[2]/p/a").click()

I am trying to identify the elements

Flights(link), origin(inputbox), destination(inputbox), date(inputbox) and search(link)

but no luck... always getting

NoSuchElementException: Message: no such element: Unable to locate element:...

I am a beginner to selenium, please help.

This is tricky because ultimately to set the departure and return dates you have to click on the calendar and select various date buttons. Perhaps a more detailed investigation might reveal a way of executing a JavaScript script to add the dates to the underlying widgets. But I will try to at least get you started. The main issue is that to enter, for example, a departure airport, you have to first click on the departure button, which then brings up a formerly hidden input area into which you can now enter your info (followed by a RETURN to close the input):

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys


driver = webdriver.Chrome(executable_path= "C:\Drivers\chromedriver")
driver.get("https://www.expedia.com/")
driver.maximize_window()
driver.implicitly_wait(5)
try:
    driver.find_element(By.XPATH, "//*[@id='uitk-tabs-button-container']/li[2]/a/span").click()

    # Leaving from:
    driver.find_element(By.XPATH, "/html/body/div[1]/div[1]/div/div[1]/div/div[1]/div[3]/div/figure/div[3]/div/div/div/div/div[2]/div/form/div[2]/div/div[1]/div/div[1]/div/div[1]/div/div/div/div/div[1]/button").click()
    driver.find_element(By.XPATH, "/html/body/div[1]/div[1]/div/div[1]/div/div[1]/div[3]/div/figure/div[3]/div/div/div/div/div[2]/div/form/div[2]/div/div[1]/div/div[1]/div/div[1]/div/div/div/div/div[2]/header/section/div/input").send_keys("BLR" + Keys.RETURN)

    # Arriving to:
    driver.find_element(By.XPATH, "/html/body/div[1]/div[1]/div/div[1]/div/div[1]/div[3]/div/figure/div[3]/div/div/div/div/div[2]/div/form/div[2]/div/div[1]/div/div[1]/div/div[2]/div/div/div/div/div[1]/button").click()
    driver.find_element(By.XPATH, "/html/body/div[1]/div[1]/div/div[1]/div/div[1]/div[3]/div/figure/div[3]/div/div/div/div/div[2]/div/form/div[2]/div/div[1]/div/div[1]/div/div[2]/div/div/div/div/div[2]/header/section/div/input").send_keys("BOM" + Keys.RETURN)

    # Departing:
    # open calendar:
    driver.find_element(By.ID, "d1-btn").click()
    input('pausing so you can see the calendar...')
    # pick dates (this is the tricky bit) -- code omitted:
    # finally click "Done":
    driver.find_element(By.XPATH, "/html/body/div[1]/div[1]/div/div[1]/div/div[1]/div[3]/div/figure/div[3]/div/div/div/div/div[2]/div/form/div[2]/div/div[1]/div/div[2]/div/div/div/div[1]/div/div[2]/div/div[2]/button").click()
finally:
    input('pausing before termination...')
    driver.quit()

Note that the browser window must have the focus (be the current window) or the find_element calls might fail. Anyway, that has been my experience.

This is what I see:
