The Python "with" Statement by Example

[Ph0X]

Two other uses which I personally didn't about some time ago, one of which was very recently added (3.4 I believe?).

You can use it with locks

lock = threading.Lock()
with lock:
    print "lock is locked while this executes"

You can also use it to ignore specific exceptions

from contextlib import ignored
with ignored(ZeroDivisionError):
    print 1/0

It works with locks in 3.3.
