returning values from threads in python can be done using a few different approaches. the most common methods include using `concurrent.futures.threadpoolexecutor`, `queue.queue`, or a custom thread class that stores results. below is an informative tutorial with examples illustrating each of these methods.

method 1: using `concurrent.futures.threadpoolexecutor`

the `concurrent.futures` module provides a high-level interface for asynchronously executing callables. the `threadpoolexecutor` can be utilized to run functions in separate threads and retrieve their results.

#### example:



method 2: using `queue.queue`

another way to return values from threads is to utilize a `queue.queue`. each thread can put its result into the queue, which can be retrieved by the main thread.

#### example:



method 3: custom thread class

you can also create a custom thread class that stores the result internally and provides a method to retrieve it after the thread has completed its execution.

#### example:



conclusion

in python, you can return values from threads using several methods, including `concurrent.futures.threadpoolexecutor`, `queue.queue`, and custom thread classes. the choice between these methods depends on your specific use case and complexity requirements.

*threadpoolexecutor* is suitable for simple cases where you want to run a function and retrieve its result easily.
*queue* is helpful when you have more complex threading scenarios, such as needing to pass multiple results back from different threads.
*custom thread class* allows for an object-oriented approach and can encapsulate thread logic and state.

feel free to choose the method that best fits your application's needs!
