Python切換中英文輸入法

要實現中英文切換，首先Windows系統必須要有中文語言和英文語言，才能實現輸入法(語言)切換。

import win32api
import win32gui
from win32con import WM_INPUTLANGCHANGEREQUEST


def change_language(language="EN"):
    """
    切換語言
    :param language: EN––English; ZH––Chinese
    :return: bool
    """
    LANGUAGE = {
        "ZH": 0x0804,
        "EN": 0x0409
    }
    hwnd = win32gui.GetForegroundWindow()
    language = LANGUAGE[language]
    result = win32api.SendMessage(
        hwnd,
        WM_INPUTLANGCHANGEREQUEST,
        0,
        language
    )
    if not result:
        return True
