tk创建数字按钮点击输入

可以使用Tkinter中的Button和Entry组件来实现该功能。具体步骤如下：

1. 导入Tkinter模块。

import tkinter as tk

2. 创建主窗口。

root = tk.Tk()

3. 创建一个Entry组件用于显示输入的数字。

entry = tk.Entry(root, width=30)
entry.pack()

4. 创建数字按钮，并为每个按钮绑定一个点击事件。

def button_click(number):
    current = entry.get()
    entry.delete(0, tk.END)
    entry.insert(0, str(current) + str(number))

button1 = tk.Button(root, text="1", command=lambda: button_click(1))
button2 = tk.Button(root, text="2", command=lambda: button_click(2))
button3 = tk.Button(root, text="3", command=lambda: button_click(3))
button4 = tk.Button(root, text="4", command=lambda: button_click(4))
button5 = tk.Button(root, text="5", command=lambda: button_click(5))
button6 = tk.Button(root, text="6", command=lambda: button_click(6))
button7 = tk.Button(root, text="7", command=lambda: button_click(7))
button8 = tk.Button(root, text="8", command=lambda: button_click(8))
button9 = tk.Button(root, text="9", command=lambda: button_click(9))
button0 = tk.Button(root, text="0", command=lambda: button_click(0))

5. 将数字按钮添加到主窗口。

button1.pack()
button2.pack()
button3.pack()
button4.pack()
button5.pack()
button6.pack()
button7.pack()
button8.pack()
button9.pack()
button0.pack()

6. 运行主循环。

root.mainloop()

完整代码如下：

import tkinter as tk

root = tk.Tk()
entry = tk.Entry(root, width=30)
entry.pack()

def button_click(number):
    current = entry.get()
    entry.delete(0, tk.END)
    entry.insert(0, str(current) + str(number))

button1 = tk.Button(root, text="1", command=lambda: button_click(1))
button2 = tk.Button(root, text="2", command=lambda: button_click(2))
button3 = tk.Button(root, text="3", command=lambda: button_click(3))
button4 = tk.Button(root, text="4", command=lambda: button_click(4))
button5 = tk.Button(root, text="5", command=lambda: button_click(5))
button6 = tk.Button(root, text="6", command=lambda: button_click(6))
button7 = tk.Button(root, text="7", command=lambda: button_click(7))
button8 = tk.Button(root, text="8", command=lambda: button_click(8))
button9 = tk.Button(root, text="9", command=lambda: button_click(9))
button0 = tk.Button(root, text="0", command=lambda: button_click(0))

button1.pack()
button2.pack()
button3.pack()
button4.pack()
button5.pack()
button6.pack()
button7.pack()
button8.pack()
button9.pack()
button0.pack()

root.mainloop()
