# 设置Chrome浏览器的驱动路径
driver_path = "path_to_chromedriver"

# 创建一个Chrome浏览器实例
driver = webdriver.Chrome(driver_path)

# 打开YouTube网站
driver.get("https://www.youtube.com/")

# 定位搜索框并输入关键词
search_box = driver.find_element_by_name("search_query")
search_box.send_keys("your_search_keyword")
search_box.send_keys(Keys.RETURN)

# 等待搜索结果加载完成
wait = WebDriverWait(driver, 10)
first_channel = wait.until(EC.presence_of_element_located((By.CSS_SELECTOR, "#channel-section a")))

# 点击第一个频道
first_channel.click()

# 关闭浏览器
driver.quit()
