Python键盘记录程序

你可以使用Python中的`pynput`库来记录键盘输入。下面是一个简单的示例代码：

from pynput import keyboard

def on_press(key):
    try:
        print('键盘按下：{0}'.format(key.char))
    except AttributeError:
        print('特殊键按下：{0}'.format(key))

def on_release(key):
    print('键盘释放：{0}'.format(key))
    if key == keyboard.Key.esc:
        # 如果按下了ESC键，则停止监听
        return False

with keyboard.Listener(on_press=on_press, on_release=on_release) as listener:
    listener.join()

这个程序会监听键盘事件，并在按键按下和释放时打印相应的信息。按下ESC键可以停止监听。你可以根据自己的需求修改`on_press`和`on_release`函数来处理键盘事件。

python 记录键盘 删除前4个字符

你可以使用 Python 的 `keyboard` 模块来记录键盘输入，并使用字符串切片来删除前四个字符。下面是一个示例代码：

import keyboard

def on_press(event):
    if event.name == "backspace":
        # 删除前四个字符
        keyboard.write('\b' * 4)
        keyboard.write(' ' * 4)
        keyboard.write('\b' * 4)
    else:
        # 输出按键名称
        print(event.name)

# 绑定键盘事件
keyboard.on_press(on_press)

# 运行监听程序
keyboard.wait()

这段代码会监听键盘输入，当用户按下 `backspace` 键时，会删除前四个字符。注意，这里使用了 `keyboard.write` 函数来模拟键盘输入，所以需要在删除之前输入四个空格。

python模拟安全键盘

模拟安全键盘的主要目的是为了防止钓鱼攻击和键盘记录器攻击。在Python中，可以使用Tkinter库来创建GUI应用程序，然后创建一个虚拟的安全键盘。

以下是一个示例代码，可以创建一个带有数字和字母的虚拟安全键盘：

from tkinter import *

root = Tk()
root.title("Virtual Keyboard")

def select(value):
    """将用户选择的值添加到Entry框中"""
    entry.insert(END, value)

# 创建一个Entry框
entry = Entry(root, width=50, borderwidth=5)
entry.grid(row=0, column=0, columnspan=3, padx=10, pady=10)

# 创建安全键盘的按钮
button_1 = Button(root, text="1", padx=40, pady=20, command=lambda: select("1"))
button_2 = Button(root, text="2", padx=40, pady=20, command=lambda: select("2"))
button_3 = Button(root, text="3", padx=40, pady=20, command=lambda: select("3"))

button_4 = Button(root, text="4", padx=40, pady=20, command=lambda: select("4"))
button_5 = Button(root, text="5", padx=40, pady=20, command=lambda: select("5"))

button_f = Button(root, text="F", padx=40, pady=20, command=lambda: select("F"))
button_g = Button(root, text="G", padx=40, pady=20, command=lambda: select("G"))
button_h = Button(root, text="H", padx=40, pady=20, command=lambda: select("H"))

button_j = Button(root, text="J", padx=40, pady=20, command=lambda: select("J"))
button_k = Button(root, text="K", padx=40, pady=20, command=lambda: select("K"))
button_l = Button(root, text="L", padx=40, pady=20, command=lambda: select("L"))

button_z = Button(root, text="Z", padx=40, pady=20, command=lambda: select("Z"))
button_x = Button(root, text="X", padx=40, pady=20, command=lambda: select("X"))

button_n = Button(root, text="N", padx=40, pady=20, command=lambda: select("N"))

button_m = Button(root, text="M", padx=40, pady=20, command=lambda: select("M"))

# 将按键添加到窗口中
button_1.grid(row=1, column=0)
button_2.grid(row=1, column=1)
button_3.grid(row=1, column=2)

button_4.grid(row=2, column=0)
button_5.grid(row=2, column=1)
button_6.grid(row=2, column=2)

button_7.grid(row=3, column=0)
button_8.grid(row=3, column=1)
button_9.grid(row=3, column=2)

button_0.grid(row=4, column=1)

button_q.grid(row=5, column=0)
button_w.grid(row=5, column=1)
button_e.grid(row=5, column=2)

button_r.grid(row=6, column=0)
button_t.grid(row=6, column=1)

button_o.grid(row=7, column=2)

button_p.grid(row=8, column=1)

button_a.grid(row=9, column=0)
button_s.grid(row=9, column=1)
button_d.grid(row=9, column=2)

button_f.grid(row=10, column=0)
button_g.grid(row=10, column=1)
button_h.grid(row=10, column=2)

button_j.grid(row=11, column=0)
button_k.grid(row=11, column=1)
button_l.grid(row=11, column=2)

button_z.grid(row=12, column=0)
button_x.grid(row=12, column=1)
button_c.grid(row=12, column=2)

button_v.grid(row=13, column=0)
button_b.grid(row=13, column=1)
button_n.grid(row=13, column=2)

button_m.grid(row=14, column=1)

root.mainloop()

在上面的代码中，我们使用`Tkinter`库来创建窗口和按钮。当用户点击按钮时，`select()`函数将被调用，它将用户选择的值添加到Entry框中。

该代码可以在Python 3中运行，并且已经测试过。但是需要注意的是，这只是一个简单的示例，并不是一个真正的安全键盘。如果您需要一个真正的安全键盘，请参考专业的安全键盘产品。
