5. logging.disable（logging.CRITICAL） #禁止

二.实例

1. import logging
2. logging.basicConfig(level=logging.DEBUG, format=' %(asctime)s - %(levelname)s- %(message)s')
3. logging.debug('Start of program')
4. def factorial(n):
5.     logging.debug('Start of factorial(%s%%)' % (n))
6.     total = 1
7. for i in range(1, n 1):
8.         total = total * i
9.         logging.debug('i is ' str(i) ', total is ' str(total))
10.     logging.debug('End of factorial(%s%%)' % (n))
11. return total
12. print(factorial(7))
13. logging.debug('End of program')
