How should I use try...except while defining a function?
- by SpawnCxy
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
