Solve the following python programming problem given the following code:
def getWindows() : 
    "Return dict: {'window title' : window handle} for all visible windows" 
    titles = { 
        
} 
    def foreach_window(hwnd, lparam) : 
        if IsWindowVisible (hwnd) : 
            length = GetWindowTextLength (hwnd) 
            buff = ctypes.create_unicode_buffer ((length + 1)) 
            GetWindowText (hwnd, buff, (length + 1)) 
            titles [buff.value] = hwnd 
return True 
EnumWindows (EnumWindowsProc (titles), 0) 
    return titles
