But is it such a good idea to do? What if critical section is at two or
more different places at once? How will you deal with
def increment(self):
try self.counter_lock:
self.counter += 1
def decrement(self):
try self.counter_lock:
self.counter -= 1
(Suppose, it's not simple or elegant to do it in one place:
def change(self, delta=1):
try self.counter_lock:
self.counter += delta
)
As for with, it could be added as follows:
try with lock:
