How to Break a While Loop with Keystrokes in Python?

Interrupting a While Loop with Keystrokes in Python

In various programming scenarios, it's common to utilize while loops for repetitive tasks. However, situations arise where you may need to provide a way for the user to terminate the loop prematurely.

To achieve this with a keystroke, one approach is to utilize Python's built-in keyboard-interrupt handling. Here's an example:

<code class="python">try:
    while True:
        # Perform desired tasks
except KeyboardInterrupt:
    # Handle interrupt (e.g., break the loop)</code>

In this scenario, when the user presses Ctrl-C, a KeyboardInterrupt exception is raised. By encompassing the loop within a try-except block and catching the KeyboardInterrupt, you can respond appropriately, such as breaking the loop.

Another method is to implement a separate thread or process to continuously monitor user keystrokes. This can provide finer control over the keystrokes that can terminate the loop, but it also introduces additional complexity.

Depending on your specific requirements, either approach can effectively enable you to terminate a while loop with a keystroke, allowing the user to control data collection and terminate it when desired.
