這是我試圖用來從 FRED 網站抓取資料以下載 CSV 格式的時間序列資料的代碼，但它正在將我重定向到另一個頁面
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
from selenium.webdriver import ActionChains
url='https://fred.stlouisfed.org/series/TERMCBAUTO48NS'
driver=webdriver.Chrome(executable_path=r'D:\\Workspace\\Python\\automation\\chromedriver.exe')
driver.get(url)
element=driver.find_element_by_id('download-button')
element.click()
wait1=WebDriverWait(driver,20)
result1=wait1.until(
EC.element_to_be_clickable((By.ID,'fg-download-menu')))
print('Result 1: ',result1)
menu=driver.find_element_by_id('fg-download-menu')
wait1=WebDriverWait(driver,20)
result2=wait1.until(
EC.element_to_be_clickable((By.ID,'download-data-csv')))
print('Result 2: ',result2)
hidden_submenu=driver.find_element_by_id('download-data-csv')
actions=ActionChains(driver)
actions.move_to_element(menu)
actions.click(hidden_submenu)
actions.perform()
driver.quit()

這應該有效：
from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
driver = webdriver.Chrome("D:/chromedriver/94/chromedriver.exe")
driver.get("https://fred.stlouisfed.org/series/TERMCBAUTO48NS")
# wait 60 seconds
wait = WebDriverWait(driver,60)
wait.until(EC.element_to_be_clickable((By.ID, "download-button"))).click()
wait.until(EC.element_to_be_clickable((By.ID, "download-data-csv"))).click()

您使用的定位器不是唯一的。就像有幾個標簽具有相同的 id download-button。
為 Elements 找到唯一的定位器很重要。你可以參考這個鏈接
嘗試如下并確認：
driver.get("https://fred.stlouisfed.org/series/TERMCBAUTO48NS")
wait = WebDriverWait(driver,30)
# Click on Download button
wait.until(EC.element_to_be_clickable((By.XPATH,"//div[@id='page-title']//button[@id='download-button']"))).click()
# Click on CSV data
wait.until(EC.element_to_be_clickable((By.XPATH,"//ul[@id='fg-download-menu']//a[@id='download-data-csv']"))).click()
