What kind of "thread safe" are deque's actually?

2023-03-27 Thread Travis Griggs
A while ago I chose to use a deque that is shared between two threads. I did so because the docs say: "Deques support thread-safe, memory efficient appends and pops from either side of the deque with approximately the same O(1) performance in either direction.”

The Python standard library module datetime seems to be what you want.  It has objects representing date/times, and deltatimes (i.e., durations).  These can be timezone aware or not as you wish. Dr. Gary Herron Professor of Computer Science DigiPen Institute of Technology On 3/27/23 6:00 AM,
