小编Log*_*ead的帖子

我用Google搜索并查看了默认文档,但我无法弄清楚为什么这不会产生三行日志记录:

# main.py
import logging
import apple
import banana

log = logging.getLogger('main')
log.setLevel(logging.DEBUG)

ch = logging.StreamHandler()
ch.setLevel(logging.DEBUG)

formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
ch.setFormatter(formatter)

log.addHandler(ch)

log.info("I'm in main!")

# apple.py
import logging

log = logging.getLogger('main.apple')
log.info("I'm here in apple!")

# banana.py
import logging

log = logging.getLogger('main.banana')
log.info("I'm here in banana!")

# output
2011-09-03 16:40:54,062 - main - INFO - I'm in main!

但是日志文档中的示例运行正常.

有任何想法吗？
