Hi all, I have a dict which looks like this..
dict={'130nm': {'umc': ['1p6m_1.2-3.3_fsg_ms']}, '180nm': {'chartered': ['2p6m_1.8-3.3_sal_ms'], 'tsmc': ['1p6m_1.8-3.3_sal_log', '1p6m_1.8-3.3_sal_ms']}, '250nm': {'umc': ['2p6m_1.8-3.3_sal_ms'], 'tsmc': ['1p6m_2.2-3.5_sal_log', '1p6m_1.8-3.3_sal_ms']} } For clarification: 130nm,180nm,250nm refer to Nodes tsmc,chartered,umc refer to Foundries 1p6m..blah, 2p6m..blah refer to Process I want a function which can do this: nodes = getNodes() should return a list [130nm,180nm,250nm] nodes = getNodes(Foundry="umc") should return a list [130nm,250nm] nodes = getNodes(Process="2p6m_1.8-3.3_sal_ms") should return a list [180nm,250nm] nodes = getNodes(Foundry="umc", Process="2p6m_1.8-3.3_sal_ms") should return a list [250nm] nodes = getNodes(Foundry="foo", Process="2p6m_1.8-3.3_sal_ms") should return None Obviously I want to extend this to Each area ( i.e., getFoundry(), getProcess() ) but I can do that. I just don't know how to easily do this reverse kind of look up? Can someone help me on this? -- http://mail.python.org/mailman/listinfo/python-list
