pyHook不让我输入

Question

我正在尝试检测python中的全局按键。(我完全是Python中的菜鸟)。我的问题是pyHook能识别我的关键事件，但它不再让我输入了。如果我试图在打开的selenium webdriver (参见代码)中键入内容，除了打印keyid之外，什么也没有发生。

下面是我的代码：

import pyHook, pythoncom, sys, win32api
from colorama import Fore, init
from selenium import webdriver

add_key = 187 #keyID for "+" key
commands = ["start", "quit", "save", "help"]
urls = []
driver = webdriver.Chrome()

def OnKeyboardEvent(event):
    print(event.KeyID)
    if event.KeyID == add_key:
        print("add key pressed")
        urls.append(driver.current_url)
    return 0

def PrintHelpMessage():
    # write help message
    MainLoop()

def MainLoop():
    print(Fore.GREEN + "type commands for more help.")

    usr_input = input()
    if usr_input == "commands":
        print(Fore.GREEN + "available commands: start, quit, save, help")
        command_input = input()
        if command_input in commands:
            if command_input == "start":
                hook_manager = pyHook.HookManager()
                hook_manager.KeyDown = OnKeyboardEvent
                hook_manager.HookKeyboard()
                pythoncom.PumpMessages()
            elif command_input == "quit":
                sys.exit(0)
            elif command_input == "save":
                # implement save function
                print("Save function implemented soon")
            elif command_input == "help":
                PrintHelpMessage()


init(autoreset = True) # init colorama -> makes it possible to use colored text in terminal
print(Fore.RED + "---easy playlist manager---")
driver.get("http://youtube.com")
MainLoop()

也许有人能告诉我怎么修？

您将在OnKeyboardEvent中返回0，因此键盘事件不会传递给其他处理程序或窗口本身。如果你不想过滤事件，你应该返回True。
