最簡單的方法是使用帶有排除標誌的grep，例如

grep -v DEBUG /tmp/exceptions.log

這將打印不行包含「調試」字符串。

>>> import re 
>>> pat = re.compile(r'(\w+:\s.*\n)') 
>>> pat.findall(c) # c is your logs content 
['IntegrityError: (1048, "Column \'option_b\' cannot be null")\n', 'IntegrityError: (1048, "Column \'option_b\' cannot be null")\n'] 
>>>

你也可以使用PyLog中的「logview」。如果您查看PyWorkbooks的最新版本（此處爲https://sourceforge.net/projects/pyworkbooks/），則會有一個easy_log文件設置日誌記錄應用程序的日誌記錄。

logview是一個很好的GUI，並允許你做一些事情，如過濾器輸入。

如果您使用try-除了結構，你可以這樣做：

try: 
    foo() 
except Exception,ex: 
    print "Exception %s"%str(ex) # Output exception 
    print "Unexpected error:", sys.exc_info()[0] # Exception message 
    import traceback 
    traceback.print_exc() # Output full traceback if you want one
