.. and why is this better than
try:
os.unlink('missing.txt')
except OSError as exc:
do_something()
It would allow you to perform a series of operations then process the any
exceptions all together e.g.
with trap(OSError) as cm1:
os.unlink('missing.txt')
with trap(OSError) as cm2:
os.unlink('other_missing.txt')
with trap(OSError) as cm3:
os.unlink('another_missing.txt')
for cm in (cm1, cm2, cm3):
if cm.exc:
do_something(cm.exc)
As long as we're having fun ;)
trap_os = suppress(OSError)
dead_files = ('missing.txt', 'other_missing.txt', 'actually_here.txt')
for file in dead_files:
with trap_os:
os.unlink(missing.txt)
for exc in trap_os.suppressed_exceptions:
do_something(exc)
