Why both, import logging and import logging.config are needed?
提问by Shefali
Should not it be handled by a single import? i.e. import logging. If I do not include import logging.config in my script, it gives :
不应该由单个导入处理吗？即导入日志。如果我的脚本中没有包含 import logging.config，它会给出：
AttributeError: 'module' object has no attribute 'config'
AttributeError: 'module' 对象没有属性 'config'

loggingis a package. Modules in packages aren't imported until you (or something in your program) imports them. You don't need both import loggingand import logging.configthough: just import logging.configwill make the name loggingavailable already.
logging是一个包。包中的模块在您（或您的程序中的某些内容）导入它们之前不会导入。你并不需要同时import logging和import logging.config虽然：只是import logging.config将名字logging可用了。

Just add an addtional explanation for Thomas's answer.
只需为托马斯的回答添加额外的解释。
loggingis a package, a directory.
logging是一个包，一个目录。
enter the logging dir and list what files there is:
输入日志目录并列出有哪些文件：
config.py handlers.py __init__.py __pycache__
config.py handlers.py __init__.py __pycache__
so, There is a config.pyfile in logging directory, but why it can't import logging.config. That's because there is no confignamespace in logging/__init__.py
所以，config.py日志目录中有一个文件，但为什么不能import logging.config。那是因为没有config命名空间 logging/__init__.py
