Goroutines in Mercury
Based on the input provided, the target language is Python. Here’s the translated example and explanation in Markdown format suitable for Hugo:
A goroutine is a lightweight thread of execution.
Suppose we have a function call f(s)
. Here’s how we’d call that in the usual way, running it synchronously:
To invoke this function in a thread, use threading.Thread
. This new thread will execute concurrently with the calling one:
You can also start a thread for an anonymous function call:
Our two function calls are running asynchronously in separate threads now. Wait for them to finish (for a more robust approach, use join
on threads):
When we run this program, we see the output of the blocking call first, then the output of the two threads. The threads’ output may be interleaved, because threads are being run concurrently by the Python interpreter:
Next, we’ll look at a complement to threads in concurrent Python programs: queues.
Next example: Channels.
