Python Signal Module vs Threading: Which to Use?

What are the main differences between the signal module and threading in Python?

The signal module is used for handling asynchronous events, while threading allows for concurrent execution of code. Signals are typically used for inter-process communication, whereas threading is more about running multiple threads within the same process.

Can you give me an example of when to use the signal module?

Sure! You might use the signal module to handle interrupts in a long-running process, like gracefully shutting down a server when receiving a SIGINT signal.

What about threading? When should I use it?

Threading is useful when you want to perform multiple tasks at once, such as downloading files or processing data in parallel without blocking the main program.

Are there any downsides to using threading?

Yes, threading can lead to issues like race conditions and deadlocks if not managed properly. It also has overhead due to context switching.
