import sys
try:
raise xxx
except str,e:
print 1,e # is not caught here
except:# is caught here
print 2,sys.exc_type,sys.exc_value
In the above code a string exception is raised which though deprecated
but still a 3rd party library I use uses it. So how can I catch such
exception
but the whole point of catching such exception is that i can print its
value
there are many such exceptions and hence it is not feasible to catch
them all or know them all unless i go thru src code.

try:
raise abc
except:
e, t, tb = sys.exc_info()
if not isinstance(e, str):
raise
print caught, e
This seems to be the solution, thanks

except TypeError,e:
print 1,e # is caught here
1 exceptions must be classes or instances, not str
doesn't happen so in 2.5.2

It would be better to write your own exception class:
class MyException(Exception):
pass
and how would i automatically inject this into 3rd part library

It will look for the existence of type(ob).__unicode__ ...

According to the below, type(ob).__str__ is tried
ok that explains it,
so
unicode(obj) calls __unicode__ on that object and if it isn't there
__repr__ is used
__repr__ of list by default return a str even if __repr__ of element
is unicode
so my only solution looks like to use my own list class everywhere i
use list
class mylist(list):
def
yes but my list sometimes have list of lists

also not sure why (python 2.5)
print a # works
print unicode(a) # works
print [a] # works
print unicode([a]) # doesn't works

Sorry being unclear again, hmm I am becoming an expert in it.
I pasted that code as continuation of my old code at start
i.e
class A(object):
def __unicode__(self):
return u©au
def __repr__(self):
return unicode(self).encode(utf-8)
__str__ = __repr__
doesn't
sorry for not being specfic and not given all info

My question has not much to do with stdout because I am able to print
unicode
so
print
First of all thanks everybody for putting time with my confusing post
and I apologize for not being clear after so many efforts.
here is my last try (you are free to ignore my request for free
advice)
# -*- coding: utf-8 -*-
class A(object):
def __unicode__(self):
return u©au
and yes replace string by u'\N{COPYRIGHT SIGN}au'
as mentioned earlier non-ascii char may not come correct posted here.
