python - 我为在日志记录模块 python 中获取 ValueError 所做的工作

Question

我想将日志写入文件和标准输出，因此我使用这段代码，但我总是在标准输出中得到这个 ValueError 而不是在文件中。

我想从 INFO 级别及更高级别进行日志记录，以获取标准输出和文件。并将 DEBUG 级别及以上级别写入文件。

import logging

logging.basicConfig(level=logging.DEBUG,
                    format='%(asctime)s %(name)-12s %(levelname)-8s %(funcName)-5s %(message)s',
                    filename='OkanimeDownloader.log',
                    filemode='w')

console = logging.StreamHandler()
console.setLevel(logging.INFO)
formatter = logging.Formatter('%(levelname):-8s %(message)s')
console.setFormatter(formatter)
logging.getLogger('').addHandler(console)



dic = {'Google Drive': 'https://docs.google.com/file/d/0B-fK-jS8DjCeYVVwRWdfWnc1YWs/preview', 'Mega': '//vk.com/video_ext.php?oid=359177611&id=456239042&hash=59d982cc2450bc8d&sd', 'Openload': 'https://openload.co/embed/MVysKUs5rm4/%5BOKanime.com%5D_s%40ks2_-_11_%28animok%29.mp4', 'Streamango': 'https://streamango.com/embed/pnfdsqnedcffrttm/_OKanime_com_s_ks2_-_11_animok_mp4', 'Cloudy': 'https://www.cloudy.ec/embed.php?id=09c53285b6ac4', 'Tune.pk': 'https://embed.tune.pk/play/7147555/okanimecom-sks2-11-animok', 'Mp4upload': 'https://www.mp4upload.com/embed-swz4hesaisnm.html'}

logging.info('The dic:  {}'.format(dic))

输出:

Answer 1

formatter = logging.Formatter('%(levelname)-8s : %(message)s')

此语法修复了 Formatter 中的错误
