我有腳本 parent.py 和 child.py（許多孩子），我需要為每個腳本創建日志，因此 parent.py 中的任何日志記錄都應該在 parent.log 中，child.py 應該在 child.log 中我在每個腳本中都有以下內容，但我得到空日志......為什么？#main.pyimport childhandler = logging.FileHandler('logs/main.log')handler.setLevel(logging.DEBUG)formatter = logging.Formatter("%(asctime)s [%(filename)s:%(lineno)s - % (funcName)10s()] %(levelname)s: %(message)s")handler.setFormatter(formatter)logger = logging.getLogger(__name__)logger.addHandler(handler)child.child_func()logger.info('testing parent...')#child.pyhandler = logging.FileHandler('logs/child.log')handler.setLevel(logging.DEBUG)formatter = logging.Formatter("%(asctime)s [%(filename)s:%(lineno)s - % (funcName)10s()] %(levelname)s: %(message)s")handler.setFormatter(formatter)logger = logging.getLogger(__name__)logger.addHandler(handler)def child_func(): logger.info('testing child...')我需要的是#parent.log{format} testing parent...#child.log{format} testing child...

上面的人對記錄器的默認級別是正確的。此外，我發現將日志配置整合到應用程序的早期階段更易于管理，而不是將您的配置分散到任何地方。請參閱下面的示例。
注意：我不希望這被選為答案。我只是想指出我認為組織代碼的更好方法。
主文件
import logging
import child
logger = logging.getLogger(__name__)
def setup_logging():
main_handler = logging.FileHandler('logs/main.log')
child_handler = logging.FileHandler('logs/child.log')
# Note that you can re-use the same formatter for the handlers.
formatter = logging.Formatter("%(asctime)s [%(filename)s:%(lineno)s - %(funcName)10s()] %(levelname)s: %(message)s")
main_handler.setFormatter(formatter)
child_handler.setFormatter(formatter)
# By default, loggers inherit the level from their parent, so we only need
# to set the level on the root logger if you want to have only one knob to
# control the level.
root_logger = logging.getLogger()
root_logger.setLevel(logging.DEBUG)
main_logger = logging.getLogger(__name__)
child_logger = logging.getLogger('child')
child_logger.propagate = False
main_logger.addHandler(main_handler)
child_logger.addHandler(child_handler)
def main():
setup_logging()
child.child_func()
logger.info('testing parent...')
if __name__ == '__main__':
main()
孩子.py
import logging
logger = logging.getLogger(__name__)
def child_func():
logger.info('testing child...')
設置根記錄器和子記錄器（無主記錄器）
這是一個設置根記錄器以登錄到的示例logs/main.log，以及將子記錄器設置為轉到的示例logs/child.log
def setup_logging():
root_handler = logging.FileHandler('logs/main.log')
child_handler = logging.FileHandler('logs/child.log')
# Note that you can re-use the same formatter for the handlers.
formatter = logging.Formatter("%(asctime)s [%(filename)s:%(lineno)s - %(funcName)10s()] %(levelname)s: %(message)s")
root_handler.setFormatter(formatter)
child_handler.setFormatter(formatter)
# By default, loggers inherit the level from their parent, so we only need
# to set the level on the root logger if you want to have only one knob to
# control the level.
root_logger = logging.getLogger()
root_logger.setLevel(logging.DEBUG)
root_logger.addHandler(root_handler)
child_logger = logging.getLogger('child')
child_logger.propagate = False
child_logger.addHandler(child_handler)

您可以在處理程序和記錄器上設置嚴重性級別 - 我相信記錄器logging.WARNING默認設置為，因此您只能使用代碼獲得警告日志。
import logging
import child
handler = logging.FileHandler('logs/main.log')
formatter = logging.Formatter("%(asctime)s [%(filename)s:%(lineno)s - %(funcName)10s()] %(levelname)s: %(message)s")
handler.setFormatter(formatter)
logger = logging.getLogger(__name__)
logger.addHandler(handler)
logger.setLevel(logging.DEBUG) # <-- changed
child.child_func()
logger.info('testing parent...')
logger.warning('testing parent...')
logger.debug('testing parent...')
#child.py
import logging
handler = logging.FileHandler('logs/child.log')
formatter = logging.Formatter("%(asctime)s [%(filename)s:%(lineno)s - %(funcName)10s()] %(levelname)s: %(message)s")
handler.setFormatter(formatter)
logger = logging.getLogger(__name__)
logger.addHandler(handler)
logger.setLevel(logging.DEBUG) # <-- changed
def child_func():
logger.info('testing child...')
logger.warning('testing child...')
logger.debug('testing child...')
