Hi all,

I find I've been confused by the problem that when I needn't to use try..except.For last few days it was used in almost every function I defined which I think maybe a bad practice.For example:

class mongodb(object):

    def getRecords(self,tname,conditions=''):
        try:
            col = eval("self.db.%s" %tname)
            recs = col.find(condition)
            return recs
        except Exception,e:
            #here make some error log with e.message

What I thought is ,exceptions may be raised everywhere and I have to use try to get them. And my question is,is it a good practice to use it everywhere when defining functions?If not are there any principles for it?Help would be appreciated!

Regards
