You can do this almost automatically with a decorator:
def in_try(func):
def wrapper(*args, **kwargs):
try:
return func(*args, **kwargs)
except:
print "entered except"
raise
return wrapper
class C(object):
@in_try
def func_a(self):
print "func_a"
@in_try
def func_b(self):
print "func_b"
raise Exception
You could probably create a metaclass to apply the wrappers automatically but I
like having it explicit as above.
