如何让python只在按下左键的情况下才播放鼠标事件记录？

pip install pyautogui

import pyautogui

def record_mouse_events():
    events = []
    is_left_button_down = False

    while True:
        event = pyautogui.waitForEvent()
        
        if event.type == 'mousedown':
            if event.button == 'left':
                is_left_button_down = True
                events.append(event)
        elif event.type == 'mouseup':
            if event.button == 'left':
                is_left_button_down = False
                events.append(event)
        elif event.type == 'mousemove':
            if is_left_button_down:
                events.append(event)
        elif event.type == 'keydown':
            if event.key == 'esc':
                break

    return events

def play_mouse_events(events):
    for event in events:
        if event.type == 'mousemove':
            pyautogui.moveTo(event.x, event.y)
        elif event.type == 'mousedown':
            pyautogui.mouseDown(button=event.button, x=event.x, y=event.y)
        elif event.type == 'mouseup':
            pyautogui.mouseUp(button=event.button, x=event.x, y=event.y)

# 示例用法
events = record_mouse_events()
play_mouse_events(events)
