[IronPython] Converting C# to Python ... the lock() keyword?

[Dino Viehland]

If you really want to use .NET monitors you can code it up as a try/finally:

Monitor.Enter(m_object)
try:
	if ...:
		...
finally:
	Monitor.Exit(m_object)

If you'd like to do a slightly more Pythonic lock you could do:

import threading

x = threading.Lock()
with x:
    pass

Or you could combine the two approaches:

from System.Threading import Monitor
class ObjectLocker(object):
    def __init__(self, obj):
            self.obj = obj
    def __enter__(self):
            Monitor.Enter(self.obj)
    def __exit__(self, *args):
            Monitor.Exit(self.obj)

with ObjectLocker(object()):
    pass
