Python 配件调拨代码实例 - 库存管理系统

以下是配件调拨的 Python 代码实例，该代码实现了一个简单的库存管理系统，包括调拨、入库、出库等功能：

class Inventory:
    def __init__(self):
        self.stock = {}

    def add_item(self, item, quantity):
        if item in self.stock:
            self.stock[item] += quantity
        else:
            self.stock[item] = quantity

    def remove_item(self, item, quantity):
        if item in self.stock:
            if self.stock[item] >= quantity:
                self.stock[item] -= quantity
            else:
                print(f'{item} inventory not enough')
        else:
            print(f'{item} not found in inventory')

    def transfer_item(self, item, quantity, from_location, to_location):
        if item in self.stock:
            if from_location in self.stock[item]:
                if self.stock[item][from_location] >= quantity:
                    if to_location in self.stock[item]:
                        self.stock[item][to_location] += quantity
                    else:
                        self.stock[item][to_location] = quantity
                    self.stock[item][from_location] -= quantity
                else:
                    print(f'{item} inventory not enough in {from_location}')
            else:
                print(f'{item} not found in {from_location}')
        else:
            print(f'{item} not found in inventory')

    def add_location(self, location):
        for item in self.stock:
            self.stock[item][location] = 0

    def remove_location(self, location):
        for item in self.stock:
            del self.stock[item][location]

    def print_inventory(self):
        for item, locations in self.stock.items():
            print(f'{item}:')
            for location, quantity in locations.items():
                print(f'	{location}: {quantity}')

# Example usage
inventory = Inventory()

# Add items to inventory
inventory.add_item('laptop', 10)
inventory.add_item('phone', 20)

# Add locations to inventory
inventory.add_location('warehouse 1')
inventory.add_location('warehouse 2')

# Transfer items between locations
inventory.transfer_item('laptop', 5, 'warehouse 1', 'warehouse 2')

# Print inventory
inventory.print_inventory()

# Remove a location from inventory
inventory.remove_location('warehouse 1')

# Remove an item from inventory
inventory.remove_item('phone', 15)

# Print inventory
inventory.print_inventory()

该代码使用了一个字典来存储库存信息，其中每个键表示一个物品，对应的值是一个字典，表示该物品在不同位置的库存数量。调拨、入库、出库等操作都是在这个字典上进行的。该代码还实现了添加、删除位置和物品的功能，并提供了一个简单的输出方法来查看当前库存状态。
