python里怎么样监控鼠标按下的是左键还是右键

我写了一个监控鼠标事件的代码，我想监控鼠标的左右按键，当我按下左键或者右键时输出并且记录下来，
但是我的这段代码好像只能对右键反应，而且点击左键的输出一样，这是哪里出问题了，希望大佬帮我看看，谢谢
对了，我的需求很简单，就是实时监控鼠标左右键，按下键时记录下来保存为npy数据。不用监控鼠标坐标

from pynput import mouse
from pynput.mouse import Button, Controller
import numpy as np
right=[]
left=[]
no=[]
mouse_out=[]
def on_move(x, y):
   print('Pointer moved to {0}'.format((x, y)))

def on_click(x, y, button, pressed):
   right_data=[]
   left_data=[]
   no=[]

   if Button.right:
      right_data = [0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0]
      #print('{0} at {1}'.format(
         #'Pressed' if pressed else 'Released',(x, y)))
      #print("右键",right_data)
   elif button == Button.left:
      left_data = [0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0]
      print('{0} at {1}'.format('Pressed' if pressed else 'Released',(x, y)))
      print("左键",left_data)
   if not pressed:
      no=[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1]
   return right_data,left_data,no
   # Stop listener

def on_scroll(x, y, dx, dy):
   print('Scrolled {0} at {1}'.format(
      'down' if dy < 0 else 'up',(x, y)))

# Collect events until released

with mouse.Listener(on_click=on_click) as listener:
   listener.join()
#print(right_data)
#np.save(r'C:\Users\Administrator\Desktop\ckpt_dir\mouse_data',right_data)

我研究了几个小时，拿别人的一个源码改了一下，基本实现实时监控鼠标左右键的点击了，但是还是有问题，第一就是太占内存了，把鼠标坐标检测打开，CPU占用70，内存60.希望有大佬能优化一下，哈哈哈
第二就是监控不知道是有错误，还是我的代码有错误，左键数值会变化，正常的是1，但是有时候会变成0，加了线程锁都没用。而且右键不是每次点击都会检测到，原因也不知道，发现自己啥也不知道。。

你用了numpy能不卡吗？
