Python in a Nutshell

Name

acquire

Synopsis

                     L.acquire(wait=True)

When wait is True, acquire locks L. If L is already locked, the calling thread suspends and waits until L is unlocked, then locks L. Even if the calling thread was the one that last locked L, it still suspends and waits until another thread releases L. When wait is False and L is unlocked, acquire locks L and returns True. When wait is False and L is locked, acquire does not affect L, and returns False.
