如何抑制Selenium控制台输出？Python脚本优化求助

我编写了一个Python脚本，可选择不同歌单并在浏览器中打开YouTube播放。但每次运行时控制台会产生大量消息，我希望能屏蔽这些消息（优先屏蔽Selenium相关，屏蔽所有也可）。我尝试了以下方法但均无效：

• 添加ChromeOptions参数：

  options = webdriver.ChromeOptions()
  options.add_argument("--log-level=OFF")
  

• 原本有options.add_experimental_option('excludeSwitches', ['enable-logging'])这行代码，删除后无变化；
• 设置driver参数：

  driver = webdriver.Chrome(service_log_path=os.devnull)
  driver = webdriver.Chrome(service_log_path='NUL')
  

控制台仍输出如下内容：

DevTools listening on ws://127.0.0.1:55146/devtools/browser/9ffb59e1-adc0-480e-835e-e36ffe7cb428

1. 优化ChromeOptions配置，屏蔽浏览器端日志 #

补充更多参数，全面抑制Chrome的各类日志输出：

options = webdriver.ChromeOptions()
# 仅保留严重错误日志
options.add_argument("--log-level=3")
# 静默模式，屏蔽所有非必要输出
options.add_argument("--silent")
options.add_argument("--disable-logging")
# 关闭日志开关和自动化提示
options.add_experimental_option('excludeSwitches', ['enable-logging', 'enable-automation'])
# 禁用自动化扩展
options.add_experimental_option('useAutomationExtension', False)

2. 通过Service类配置Selenium日志路径（Selenium 4+） #

Selenium 4之后需要通过Service类来指定日志路径，而非直接在driver构造函数中传入：

from selenium.webdriver.chrome.service import Service
import os

# 将日志导向空设备，Windows可用'NUL'替代os.devnull
service = Service(service_log_path=os.devnull)
driver = webdriver.Chrome(options=options, service=service)

3. 捕获特定异常，避免栈信息输出 #

针对脚本中出现的NoSuchWindowException，用try-except块包裹相关代码，阻止异常栈打印：

import selenium.common.exceptions

try:
    driver.fullscreen_window()
except selenium.common.exceptions.NoSuchWindowException:
    pass  # 可根据需求替换为自定义处理逻辑

4. 重定向Python全局输出流（终极方案） #

如果上述方法仍有遗漏日志，可直接在脚本开头将标准输出和错误输出重定向到空设备，彻底屏蔽所有控制台信息：

import sys
import os

# 重定向stdout和stderr到空设备
sys.stdout = open(os.devnull, 'w')
sys.stderr = open(os.devnull, 'w')

注意：该方法会屏蔽所有输出，包括你自己添加的调试打印，需谨慎使用。
