getting errno from OSError exception?

[Mark Harrison]

Can somebody loan me a clue as to how to check the errno on
an OSError, as described below?

try:
os.makedirs(d)
except OSError:
# if errno == 17 then silently ignore the error because the
# other process won the race condition and created the directory
# otherwise, allow the exception to percolate up the call stack
# and be caught by the standard error reporter


Many TIA!
Mark

What about this?

try:
os.makedirs(d)
except OSError, e:
if e.errno == 17:
do_something
