Python 3 Single Threaded Ping Sweeper
I wouldn’t suggest this code be used for production (it’s very slow). We are using to demonstrate the difference in multi threading and single threading.
This is the single threaded version of the ping sweeper. The multi threaded version of the python pingsweeper is also available to study.
