To get a return value from a thread in Python, you can use the `Thread` class from the `threading` module along with the `join()` method. By calling the `join()` method on the thread object, you can wait for the thread to finish execution and obtain its return value.<\/p>\n

Here’s an example code snippet demonstrating how to get a return value from a thread in Python:<\/p>\n

“`python
\nimport threading<\/p>\n

def calculate_sum(a, b):
\n return a + b<\/p>\n

def thread_function():
\n global result
\n result = calculate_sum(10, 20)<\/p>\n

result = None
\nthread = threading.Thread(target=thread_function)
\nthread.start()
\nthread.join()<\/p>\n

print(“Result from thread:”, result)
\n“`<\/p>\n

In this example, the `thread_function` is executed in a separate thread, and the return value from the `calculate_sum` function is stored in the `result` variable. By calling `thread.join()`, the main thread waits for the thread to finish and retrieves the return value.<\/p>\n

**The key steps to get a return value from a thread in Python are to use the Thread class from the threading module, call the join() method on the thread object, and store the return value in a variable accessible to the main thread.**<\/p>\n
