我正面临字典这个奇怪的问题。我有 2 部词典 source_dict 和 target_dict。source_dict 由它自己的逻辑组成。我正在尝试使用 source_dict 派生 target_dict。下面是我的代码。来源字典: { "t1": { "t1c": 92074660, "t1p": 92074660, "t1l": 0, "s1": { "s1c": 1558475, "s1p": 1558475, "s1l": 0, "s1t1": { "s1t1c": 1558475, "s1t1p": 1558475, "s1t1l": 0 } }, "s2": { "s2c": 4439058, "s2p": 4439058, "s2l": 0, "s2t1": { "s2t1c": 83946, "s2t1p": 83946, "s2t1l": 0 }, "s2t2": { "s2t2c": 4355112, "s2t2p": 4355112, "s2t2l": 0 } } }}预期的 target_dict : { "c": 5341515, "p": 5341515, "l": 0, "s1": { "s1c": 5341515, "s1p": 5341515, "s1l": 0, "s1t1": { "s1t1c": 5341515, "s1t1p": 5341515, "s1t1l": 0 } }}算术计算:c = source_dict(t1.t1c + t2.t2c + t3.t3c)s1c = source_dict(t1.s1.s1c + t2.s1.s1c + t3.s1.s1c)我的逻辑:for k, v in source_dict.items(): for s, offset in v.items(): if isinstance(offset, dict): for tpc, val in offset.items(): if 'c' not in tpc and 'p' not in tpc and 'l' not in tpc: if tpc not in target_dict[s].keys(): target_dict[s][tpc] = val else: target_dict[s][tpc]['c'] = target_dict[s][tpc]['c'] + val['c'] target_dict[s][tpc]['p'] = target_dict[s][tpc]['p'] + val['p'] target_dict[s][tpc]['l'] = target_dict[s][tpc]['l'] + val['l']问题:使用此逻辑,它也在更新 source_dict 中的值。我可以得到一些帮助来理解到底是什么地方出了问题,这使得 source_dict 得到新计算值的更新吗?

source_dict
虽然分配给 的位置不是很明显,但我猜 python 将变量(尤其是or 或)视为指针target_dict
的相同条件仍然适用。你只需要制作一个源字典。
