Double-Tap Shutdown Script

This Python script allows users to shut down their computer by double-tapping the Enter key. It utilizes the `keyboard` library to detect key presses and the `os` library to execute system commands. Upon running the script, users are prompted to double-tap the Enter key within a certain time threshold to initiate the shutdown process. The double-tap threshold can be adjusted based on user preferences.

1. The script begins by importing necessary libraries: `keyboard`, `time`, and `os`.

2. The `shutdown()` function is defined, which prints a message indicating that the computer is shutting down and then executes the shutdown command using `os.system()`.

3. The main block of the script checks if it's being run directly (`if __name__ == "__main__":`), and if so, it provides instructions to the user to double-tap the Enter key for shutting down the computer.

4. Variables are initialized using a list to store the timestamp of the last Enter key press (`last_enter_press_time`) and the threshold for detecting a double-tap (`double_tap_threshold`). The threshold can be adjusted to suit the user's preferences.

5. A callback function `on_enter_key(e)` is defined to handle Enter key presses. Inside this function:

   - The current time is recorded.

   - It checks if the time elapsed since the last Enter key press is less than the double-tap threshold. If so, it calls the `shutdown()` function to initiate the shutdown process.

   - Updates the `last_enter_press_time` with the current time.

6. The script sets up an event handler using `keyboard.on_press_key()` to monitor Enter key presses and call the `on_enter_key()` function.

7. The script keeps running until the 'esc' key is pressed (`keyboard.wait('esc')`), allowing the user to exit the script at any time.

import keyboard

import time

import os

def shutdown():

    print("Shutting down...")

    os.system("shutdown /s /t 1")

if __name__ == "__main__":

    print("Double-tap the Enter key to shut down the computer.")

    # Initialize variables using a list

    last_enter_press_time = [0]

    double_tap_threshold = 0.3  # Adjust this threshold as needed

    # Function to handle Enter key presses

    def on_enter_key(e):

        current_time = time.time()

        # Check if it's a double-tap

        if current_time - last_enter_press_time[0] < double_tap_threshold:

            shutdown()

        last_enter_press_time[0] = current_time

    # Set up the event handler for the Enter key

    keyboard.on_press_key('enter', on_enter_key)

    # Keep the script running

    keyboard.wait('esc')  # Press the 'esc' key to exit the script
