python-3.x - Python 抑制特定的输出消息

Question

我正在使用 tldextract 库在 Python 中解析 URL。当我运行它时，它会生成许多我想要抑制的 FILELOCK 消息。我不想抑制任何其他标准输出消息（我有很多日志消息 - 我想查看的信息）。我正在使用多处理并使用笔记本电脑的所有 8 个内核在大量 URL 上运行。

有什么建议么？以下是详细信息：

示例代码如下。我尝试使用 contextlib（https://docs.python.org/3/library/contextlib.html#contextlib.redirect_stdout）。但是，也许我没有正确使用它。

import io, tldextract, contextlib, os

def get_sld(self, reg_domain_name):
    """
    Get only the second-level domain.
    :param reg_domain_name: sports.cnn.com
    :return: cnn
    """
    domain = reg_domain_name
    #f = io.StringIO()
    with contextlib.redirect_stdout(os.devnull):
        if reg_domain_name:
            try:
                ext = tldextract.extract(reg_domain_name)
            except:
                logger.info(f'Unable to extract domain from {reg_domain_name}. Using given fqdn.')
            else:
                domain = ext.domain

    return domain

上面的代码生成了许多类似下面的消息..我想禁止：
