在 python 中按下键时记录鼠标单击并在释放相同键时停止记录

Question

我正在创建一个脚本，如果用户按下 f7，它将开始记录鼠标点击，当他释放按钮时，它应该停止，除非用户关闭程序，否则会发生这种情况。

我写了一个代码，它在按下 f7 时开始记录键，但是当释放它时它仍然记录键也因为键处于连续按下的位置，它继续启动多个侦听器并且数据不断变得冗余。

同样释放f7后，监听器并没有停止

这是代码

from pynput import mouse, keyboard
from pynput.keyboard import Key, Listener
import pickle

x_pos = []
y_pos = []
both_pos = []
file = open("test.txt", "wb")
file.close()

def on_press(key):

    mouse_listener = mouse.Listener(on_click=on_click)
    if (key==keyboard.Key.f7):
        mouse_listener.start()
        print("done")
def on_release(key):    
    if (key==keyboard.Key.f7):
        mouse_listener.stop()
        print("closing file")
        #file.close()
def on_click(x, y, button, pressed):
    if pressed:
        print ("{0} {1}".format(x,y))
        x_pos.append("{0}".format(x,y))
        y_pos.append("{1}".format(x,y))
        #print (x_pos)
        #print (y_pos)      
        both_pos = x_pos, y_pos
        with open("temp.txt", "ab") as file:
            pickle.dump(both_pos, file)
        print(both_pos)
mouse_listener = mouse.Listener(on_click=on_click)
#mouse_listener.start()
with keyboard.Listener(on_press = on_press, on_release = on_release) as listener:
    try:
        #listener.start()
        listener.join()
    except MyException as e:
        print('Done'.format(e.args[0]))

Answer 1

您在 on_release 和 on_press 中没有引用相同的 mouse_listener。
取出on_press中的mouse_listener = mouse.Listener(on_click=on_click)，在on_press和on_release

前定义mouse_listener

mouse_listener = mouse.Listener(on_click=on_click)

def on_press():
    # do on press stuff with mouse_listener
    pass

def on_release():
    # do on release stuff with mouse_listener
    pass

也可能值得将整个内容包装在 class

中
