如何使用python从打印菜单中获取用户选择的值？

def print_menu():
    print("请选择一个选项：")
    print("1. 选项一")
    print("2. 选项二")
    print("3. 选项三")

def get_user_choice():
    user_choice = input("请输入选项的数字：")
    return user_choice

def process_choice(choice):
    if choice == "1":
        print("你选择了选项一！")
    elif choice == "2":
        print("你选择了选项二！")
    elif choice == "3":
        print("你选择了选项三！")
    else:
        print("无效的选项！")

# 主程序
print_menu()
user_choice = get_user_choice()
process_choice(user_choice)
