Keyboard key events
Brief introduction of the code to press until it is released before proceeding
Function introduction:
Enter the method, press the space, and output the record. If it is not released within 5s, a prompt will pop up. If it is released, the keyboard release event will be cleared, the timer will be cleared, and the number of records will be entered into the next cycle. Conditions can be added to the bouncing method to determine when to end the loop.
