尝试索引python dict时出现语法错误:
(Pdb) o_model.flows
{(<oemof.solph.network.Bus object at 0x7f3e9c6b3ea8>, <oemof.solph.network.Transformer object at 0x7f3e9c52ce08>): <oemof.solph.network.Flow object at 0x7f3e9c50d5f8>}
这是字典的关键。:
(Pdb) o_model.flows.keys()
dict_keys([(<oemof.solph.network.Bus object at 0x7f3e9c6b3ea8>, <oemof.solph.network.Transformer object at 0x7f3e9c52ce08>)])
所以我假设字典的关键是(<oemof.solph.network.Bus object at 0x7f3e9c6b3ea8>, <oemof.solph.network.Transformer object at 0x7f3e9c52ce08>)
问题是我在尝试o_model.flows使用上面提到的键索引 时遇到语法错误。
通常我希望通过获取<oemof.solph.network.Flow object at 0x7f3e9c50d5f8>dict的 value( ),但我得到了一个语法错误:
(Pdb) o_model.flows[(<oemof.solph.network.Bus object at 0x7f3e9c6b3ea8>, <oemof.solph.network.Transformer object at 0x7f3e9c52ce08>)]
*** SyntaxError: invalid syntax
我做错了什么?
一些额外的:
(Pdb) type(o_model.flows)
<class 'dict'>
