最简单的方法是使用带有排除标志的grep，例如

grep -v DEBUG /tmp/exceptions.log

这将打印不行包含“调试”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（此处为https://sourceforge.net/projects/pyworkbooks/），则会有一个easy_log文件设置日志记录应用程序的日志记录。

logview是一个很好的GUI，并允许你做一些事情，如过滤器输入。

如果您使用try-除了结构，你可以这样做：

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
