如何修复Python Pywinauto KeySequence错误

问题描述

我正在尝试在脚本中输入（Alt + Windows键）到我的应用程序。我定义了type_keys

def type_keys(string,element):

    """Type a string char by char to Element window"""

    for char in string:

        element.type_keys(char)

然后在保存期间调用它：

              # Save

              print("Saving")

              type_keys("%{VK_LWIN down}",win)

              #wait_win_ready(win)

              time.sleep(10)

              type_keys("1",win)

              win.wait("enabled",timeout = REFRESH_TIMEOUT)

我收到一个错误，似乎我的语法不正确-但不确定如何解决。

希望为我收到此错误的原因提供帮助！感谢您的阅读。

解决方法

这是此行中的错字：type_keys("%{VK_LWIN down}",win)应该是element.type_keys("%{VK_LWIN down}")

问题是您对type_keys的实现将序列展开为如下所示：

element.type_keys("%")
element.type_keys("{") # fails here,absolutely expected!
element.type_keys("V")
element.type_keys("K")
element.type_keys("_")
element.type_keys("L")
element.type_keys("W")
element.type_keys("I")
element.type_keys("N")
element.type_keys(" ") # it won't be typed without param `with_spaces=True` (default is False)
element.type_keys("d")
element.type_keys("o")
element.type_keys("w")
element.type_keys("n")
element.type_keys("}")
