请帮我写出这个函数 def show_list(user_role, list_type,object_list), 功能是Prints out the different types of list. In this system, there are three types of lists - “Customer”, “Product” and “Order”. If user_role is “customer”, only product list and order list can be displayed. If user_role is “admin”, all types of list can be displayed. The output list should also show the row number, the page number and the total page number

好的，这是您需要的函数代码：

def show_list(user_role, list_type, object_list):
    ROWS_PER_PAGE = 10  # 每页显示的行数
    if user_role == "customer":
        if list_type == "Customer":
            print("You do not have permission to access this list.")
            return
    page_num = 1  # 当前页码
    total_pages = (len(object_list) + ROWS_PER_PAGE - 1) // ROWS_PER_PAGE  # 总页数
    while True:
        print(f"\n{list_type} List\n{'-'*50}")
        start_index = (page_num - 1) * ROWS_PER_PAGE
        end_index = start_index + ROWS_PER_PAGE
        page_list = object_list[start_index:end_index]
        for i, obj in enumerate(page_list, start=start_index+1):
            print(f"{i}. {obj}")
        print(f"\nPage {page_num}/{total_pages}")
        user_input = input("Enter 'n' for next page, 'p' for previous page, or 'q' to quit: ")
        if user_input == "n" and page_num < total_pages:
            page_num += 1
        elif user_input == "p" and page_num > 1:
            page_num -= 1
        elif user_input == "q":
            break
        else:
            print("Invalid input, please try again.")

这个函数的功能是打印出不同类型的列表。在这个系统中，有三种类型的列表 - “Customer”、“Product”和“Order”。如果用户角色是“customer”，则只能显示产品列表和订单列表。如果用户角色是“admin”，则可以显示所有类型的列表。输出的列表还应显示行号、页码和总页数。
