python - 迭代列表删除值

问题描述

我正在做一个 python 代码来基本上过滤掉该代码应该工作的具有最低值的项目，但是发生了一些奇怪的事情，例如项目 1 中的一些东西被删除了，而项目 2 中的一些东西也被删除了。任何帮助，将不胜感激。这个问题是重复的答案可以在这里看到如何在迭代时从列表中删除项目？.

items=[['Yellow Goblin Egg', 25000], ['Yellow Goblin Egg', 46000], ['Yellow Goblin Egg', 46000], ['Yellow Goblin Egg', 46000], ['Yellow Goblin Egg', 46000], ['Yellow Goblin Egg', 46000], ['Yellow Goblin Egg', 46000], ['Yellow Goblin Egg', 50000], ['Yellow Goblin Egg', 58000], ['Yellow Goblin Egg', 59000], ['Yellow Goblin Egg', 60000], ['Yellow Goblin Egg', 60000], ['Yellow Goblin Egg', 70000], ['Yellow Goblin Egg', 70000], ['Yellow Goblin Egg', 72000], ['Yellow Goblin Egg', 73000], ['Yellow Goblin Egg', 73000], ['Yellow Goblin Egg', 73000], ['Yellow Goblin Egg', 73000], ['Yellow Goblin Egg', 73000], ['Yellow Goblin Egg', 73000], ['Yellow Goblin Egg', 73000], ['Yellow Goblin Egg', 73000], ['Yellow Goblin Egg', 73000], ['Yellow Goblin Egg', 73000], ['Yellow Goblin Egg', 74000], ['Yellow Goblin Egg', 75000], ['Yellow Goblin Egg', 80000], ['Yellow Goblin Egg', 130000], ['Yellow Goblin Egg', 200000], ['Yellow Repelling Candle', 1300000], ['Yellow Repelling Candle', 1500000], ['Forceful Yellow Crab Hat of Celebration', 14999999], ['Hurtful Yellow Crab Hat of Celebration', 15000000], ['Bloody Yellow Crab Hat of Celebration', 15000000], ['Yellow Crab Hat of Celebration', 15000000], ['Itchy Yellow Crab Hat of Celebration', 16600000], ['Itchy Yellow Crab Hat of Celebration', 16800000], ['Bloody Yellow Crab Hat of Celebration', 17777777], ['Yellow Crab Hat of Celebration', 18000000], ['Yellow Crab Hat of Celebration', 18990000], ['Yellow Crab Hat of Celebration', 19000000], ['Itchy Yellow Crab Hat of Celebration', 20000000], ['Shaded Yellow Crab Hat of Celebration', 20444000], ['Shaded Yellow Crab Hat of Celebration', 25000000], ['Itchy Yellow Crab Hat of Celebration', 30000000], ['Yellow Crab Hat of Celebration', 30000000], ['Yellow Goblin Egg', 40000000], ['Neon Yellow Sheep Skin', 42000000], ['Neon Yellow Sheep Skin', 43000000], ['Neon Yellow Sheep Skin', 44000000], ['Neon Yellow Sheep Skin', 58000000], ['Neon Yellow Sheep Skin', 59700000], ['Unpleasant Yellow Crab Hat of Celebration', 75000000]]
    items2 = items
    for y in items2:
        for z in items2:
            if y[0] == z[0] and y[1] >= z[1]:
                print(y, y[1],z,z[1])
                items.remove(y)
                break
            continue
    print("/n")
    print(items2)
    print(items)

解决方案

items2 = items不会创建列表的副本，而只是对其的引用。你可能想使用items2 = items[:]
