使用Python语言完成图书类别管理功能的开发，要求该功能至少包括：输出图书类别管理主菜单、添加图书类别信息、删除图书类别信息、修改图书类别信息、显示所有图书类别信息。要求将图书类别存储到booktype.csv文件中，

好的，这是一个关于图书类别管理的Python程序开发问题。以下是一个简单的实现：

import csv

def print_menu():
    print("图书类别管理系统")
    print("1. 添加图书类别")
    print("2. 删除图书类别")
    print("3. 修改图书类别")
    print("4. 显示所有图书类别")
    print("0. 退出系统")

def add_book_type():
    book_type = input("请输入图书类别：")
    with open("booktype.csv", "a", newline="") as csvfile:
        writer = csv.writer(csvfile)
        writer.writerow([book_type])
    print("添加成功！")

def delete_book_type():
    book_type = input("请输入要删除的图书类别：")
    with open("booktype.csv", "r") as csvfile:
        reader = csv.reader(csvfile)
        rows = [row for row in reader if row[0] != book_type]
    with open("booktype.csv", "w", newline="") as csvfile:
        writer = csv.writer(csvfile)
        writer.writerows(rows)
    print("删除成功！")

def modify_book_type():
    old_book_type = input("请输入要修改的图书类别：")
    new_book_type = input("请输入新的图书类别：")
    with open("booktype.csv", "r") as csvfile:
        reader = csv.reader(csvfile)
        rows = [row if row[0] != old_book_type else [new_book_type] for row in reader]
    with open("booktype.csv", "w", newline="") as csvfile:
        writer = csv.writer(csvfile)
        writer.writerows(rows)
    print("修改成功！")

def show_book_type():
    with open("booktype.csv", "r") as csvfile:
        reader = csv.reader(csvfile)
        for row in reader:
            print(row[0])

if __name__ == "__main__":
    while True:
        print_menu()
        choice = input("请选择操作：")
        if choice == "1":
            add_book_type()
        elif choice == "2":
            delete_book_type()
        elif choice == "3":
            modify_book_type()
        elif choice == "4":
            show_book_type()
        elif choice == "0":
            break
        else:
            print("输入错误，请重新输入！")

这个程序实现了图书类别管理系统的基本功能，包括添加、删除、修改和显示所有图书类别信息。图书类别信息被存储到一个名为booktype.csv的CSV文件中。用户可以通过输入相应的选项来执行不同的操作。
