用python编程一个疫情物资管理系统程序

好的，我可以为您提供一个简单的疫情物资管理系统的Python程序，供您参考：

import csv

class Material:
    def __init__(self, name, amount, location):
        self.name = name
        self.amount = amount
        self.location = location

class MaterialManager:
    def __init__(self):
        self.materials = []

    def load_materials(self, filename):
        with open(filename, 'r') as file:
            reader = csv.reader(file)
            for row in reader:
                name = row[0]
                amount = int(row[1])
                location = row[2]
                self.materials.append(Material(name, amount, location))

    def save_materials(self, filename):
        with open(filename, 'w', newline='') as file:
            writer = csv.writer(file)
            for material in self.materials:
                writer.writerow([material.name, material.amount, material.location])

    def list_materials(self):
        for material in self.materials:
            print(f"{material.name}: {material.amount} ({material.location})")

    def add_material(self, name, amount, location):
        self.materials.append(Material(name, amount, location))

    def remove_material(self, name):
        for material in self.materials:
            if material.name == name:
                self.materials.remove(material)

    def update_material(self, name, amount, location):
        for material in self.materials:
            if material.name == name:
                material.amount = amount
                material.location = location

manager = MaterialManager()

while True:
    print("1. Load materials")
    print("2. Save materials")
    print("3. List materials")
    print("4. Add material")
    print("5. Remove material")
    print("6. Update material")
    print("7. Quit")
    choice = input("Enter your choice: ")

    if choice == '1':
        filename = input("Enter filename: ")
        manager.load_materials(filename)
    elif choice == '2':
        filename = input("Enter filename: ")
        manager.save_materials(filename)
    elif choice == '3':
        manager.list_materials()
    elif choice == '4':
        name = input("Enter name: ")
        amount = int(input("Enter amount: "))
        location = input("Enter location: ")
        manager.add_material(name, amount, location)
    elif choice == '5':
        name = input("Enter name: ")
        manager.remove_material(name)
    elif choice == '6':
        name = input("Enter name: ")
        amount = int(input("Enter amount: "))
        location = input("Enter location: ")
        manager.update_material(name, amount, location)
    elif choice == '7':
        break
    else:
        print("Invalid choice. Please try again.")

这个程序使用了一个Material类来表示物资的信息，MaterialManager类来管理物资的增删改查操作。用户可以通过控制台输入数字选择不同的操作，如加载物资、保存物资、列出物资、添加物资、删除物资和更新物资等。所有的物资信息都存储在一个CSV文件中，可以通过读写文件来实现物资信息的持久化。
