Question

将dict更改为dict2

dict = {'1':[2,3,4,5]  '2':[3,4,6]}


dict2 = {'1':{2:1,3:1,4:1,5:1}, '2':{3:1,4:1,6:1}

Answer 1

您可以使用Imports InputHelperLib Public Class ThisAddIn Dim KeyboardHook As InputHelper.Hooks.LocalKeyboardHook Private Sub ThisAddIn_Startup() Handles Me.Startup KeyboardHook = New InputHelper.Hooks.LocalKeyboardHook AddHandler KeyboardHook.KeyDown, AddressOf KeyboardHook_KeyDown AddHandler KeyboardHook.KeyUp, AddressOf KeyboardHook_KeyUp End Sub Private Sub ThisAddIn_Shutdown() Handles Me.Shutdown If KeyboardHook IsNot Nothing Then KeyboardHook.Dispose() End Sub Private Sub KeyboardHook_KeyDown(sender As Object, e As InputHelper.Hooks.KeyboardHookEventArgs) If e.Modifiers = InputHelper.ModifierKeys.Alt AndAlso e.KeyCode = System.Windows.Forms.Keys.M Then System.Windows.Forms.MessageBox.Show("ALT + M was pressed!") End If End Sub Private Sub KeyboardHook_KeyUp(sender As Object, e As InputHelper.Hooks.KeyboardHookEventArgs) If e.Modifiers = InputHelper.ModifierKeys.Alt AndAlso e.KeyCode = System.Windows.Forms.Keys.M Then System.Windows.Forms.MessageBox.Show("ALT + M was released!") End If End Sub End Class 方法：

dict.fromkeys

d = {'1': [2,3,4,5], '2': [3,4,6]} dict2 = {k: dict.fromkeys(v, 1) for k, v in d.items()} 变为：

dict2
