Sometimes you need to increment some numbers … atomically … in python.

GCC's Atomic Builtins_.
Its value is a C
long which can be incremented, decremented, and set
atomically. It is inspired by Java’s
>>> from atomiclong import AtomicLong >>> a = AtomicLong(0) >>> a += 1 >>> a.value 1 >>> a += 10 >>> a.value 11 >>> a.value = 1000 >>> a.value 1000 >>> a -= 100 >>> a.value 900
