问题描述
我想知道弓箭如何在Python中实现两键组合.我正在使用turtle.onkey()函数，因为我正在使用乌龟图形，但是它似乎不是很通用，因为我找不到找到键组合的方法.因此，是否可以使用其他方式在 python 中实现组合键?非常感谢您对此问题的任何帮助！ :)
I am wondering about bow to implement two-key combinations in Python. I am utilizing the turtle.onkey() function since I am using turtle graphics, but it seems like it is not very versatile, as I cannot find a way for it to take key combinations. So, is there any other way to implement key combinations in python? Any help regarding this issue is very much appreciated! :)
推荐答案
我使用pykeyboard(在Python 2.7中)同时按下"两个键盘键作为热键. pykeyboard软件包随 PyUserInput 安装一起安装.
I use pykeyboard ( with Python 2.7 ) to "simultaneously press" 2 keyboard keys as a hotkey. The pykeyboard package comes installed with the PyUserInput installation.
代码示例:如果我想自动让我的程序按热键组合(CTRL + P)来打印某些东西，而无需用手指在键盘上，这是通过pykeyboard进行的操作.
Code Example : If I want to automatically have my program hit the hotkey combination ( CTRL + P ) to print something without me laying a finger on the keyboard, here is how I would do it through pykeyboard.
import pykeyboard
keyboard_object = pykeyboard.PyKeyboard()
我首先创建如上所述的键盘对象.
I begin by creating my keyboard object as shown above.
keyboard_object.press_key ( keyboard_object.control_key )
keyboard_object.tap_key ( "P" ) # Upper-Case
keyboard_object.release_key ( keyboard_object.control_key )
那应该会弹出打印窗口，我可以让我的脚本按Enter键，使它继续以默认设置打印.
That should bring up the print window and I could have it continue forward to print on the default setting by having my script hit the Enter Key.
keyboard_object.tap_key ( keyboard_object.enter_key )
我什至可以拥有自己的脚本类型自定义字符串.如果我想以自动形式通过指定的字符串保存文件，这将很有用.我将从(CTRL + S)热键组合开始.
I can even have my script type custom strings. This can be useful if I want to save a file by a specified string in an automated form. I'll begin with the ( CTRL + S ) hotkey combination.
keyboard_object.press_key ( keyboard_object.control_key )
keyboard_object.tap_key ( "S" ) # Upper-Case
keyboard_object.release_key ( keyboard_object.control_key )
应弹出另存为"窗口，提示我指定要保存的文件名.所以我将其作为字符串传递.
The "Save-As" window should pop up, prompting me to specify the filename that I want to have saved. So I'll pass that as a string.
keyboard_object.type_string ( "MyFilename-03_22_2016.html" )
keyboard_object.tap_key ( keyboard_object.enter_key )
Voila！
