设置输入值以获取变量

# 获取用户输入
user_input = input("请输入一个数字: ")

# 将输入转换为整数
try:
    number = int(user_input)
    print(f"你输入的数字是: {number}")
except ValueError:
    print("输入无效，请输入一个整数。")

import tkinter as tk

def on_submit():
    user_input = entry.get()
    try:
        number = int(user_input)
        result_label.config(text=f"你输入的数字是: {number}")
    except ValueError:
        result_label.config(text="输入无效，请输入一个整数。")

# 创建窗口
window = tk.Tk()

# 创建输入框和标签
entry = tk.Entry(window)
entry.pack()

submit_button = tk.Button(window, text="提交", command=on_submit)
submit_button.pack()

result_label = tk.Label(window, text="")
result_label.pack()

# 运行窗口主循环
window.mainloop()
