Python日誌記錄：禁用的反向效果（）

Question

logging docs說調用​​方法可以「暫時限制整個應用程序的日誌記錄輸出」，但我無法找到「暫時的」。舉個例子來說，下面的腳本：

import logging 
logging.disable(logging.CRITICAL) 
logging.warning("test") 
# Something here 
logging.warning("test") 

到目前爲止，我一直沒能找到Something here，將重新啓用日誌記錄系統作爲一個整體，使第二warning打通。是否有與disable()相反的內容？

Answer 1

logging.disable(logging.NOTSET)  

Answer 2

基於由@unutbu答案，我創建了一個上下文管理器：

import logging 
log = logging.getLogger(__name__) 

class SuppressLogging: 
    """ 
    Context handler class that suppresses logging for some controlled code. 
    """ 

    def __init__(self, loglevel): 
     logging.disable(loglevel) 
     return 

    def __enter__(self): 
     return 

    def __exit__(self, exctype, excval, exctraceback): 
     logging.disable(logging.NOTSET) 
     return False 

if __name__ == "__main__": 
    logging.basicConfig(level=logging.INFO) 
    log.info("log this") 
    with SuppressLogging(logging.WARNING): 
     log.info("don't log this") 
     log.warning("don't log this warning") 
     log.error("log this error while up to WARNING suppressed") 
    log.info("log this again")
