How to catch error

[dazzler]

I have this one code, where I have to catch a specific error code. (I'm using win xp)

data = connection.recv (8048)

without any error catching, I get error message:
"error: (10035, "The socket operation could not complete without blocking")
I need to identify this error message 10035 in my code but dont know how to do it.

I tried:

[code=python]
try:
data = connection.recv (8048)
except (error):
print error
[/code]
it now prints <class 'socket error'> , and I want it to print that 10035error (and then handle it ofcourse)

I get somewhere the following code, but this doesn't work either:

[code=python]
import errno
...

try:
data = connection.recv (8048)
except, (error,message) :
print error
if error == errno.WSAEWOULD BLOCK:
print "10035 error found, doing something..."
[/code]

I don't understand that "," mark after the except, so the code gives me syntax error right away because of that... but in the code the error message should be a tuplet which I save to these variables and then see if the error code matches errno.WSAEWOULD BLOCK (that's the (windows) error 10035)

could anyone help me? =)

argh, I already found out the solution ;-D

it should be:
except Exception, (error, message):
not:
except, (error, message):

well, maybe this message will help someone else too who's having problems catching specific error codes...

argh, I already found out the solution ;-D

well, it isn't working so well after all =D

because there is also other error which must be caught

except Exception, (error, message):
handles all exception, I want it to handle only this "10035 error" because when there happends other exception (socket timeout) I got this error:
....
Traceback (most recent call last):
....
except Exception, (error, message):
ValueError: need more than 1 value to unpack

so the expection is wrongly formatted to this other expection, uhm =(

[code=python]
try:
connection, address = s.accept()
data = connection.recv (8048)
except socket.error:
[/code]
this doesn't work, I get:
"AttributeError : '_socketobject' object has no attribute 'error' "

there is socket.timeout exception in socket module but I don't know how to use it =/

ok, I solved this, but I think that there's also better solution, I dont want to compare that "timed out" string ;)

[code=python]
try:
connection, address = s.accept()
data = connection.recv (8048)

except Exception, errorcode:
if errorcode[0] == "timed out":
print "time out, doing something..."
elif errorcode[0] == 10035:
print "error 10035, doing something..."
[/code]

[CODE="python"]try:
connection, address = s.accept()
data = connection.recv (8048)

except socket.timeout:
print "time out, doing something..."
except Exception, errorcode:
if errorcode[0] == 10035:
print "error 10035, doing something..."[/CODE]

I don't know if that will help you any, posting two months later, but that should be how to handle multiple exceptions.
