dicts in python are heavily optimized. Creating a dict from N keys or key/value pairs is O(N), fetching is O(1), putting is amortized O(1), and so forth. You don't need to optimize them explicitly. You can be sure of this as python under the hood implements its own classes using ... Read More

There are many C++/Python bindings. It boils down to what you use to communicate between C++ and python to read python dictionaries in c++. Most of these libraries(like Boost) handle the parsing themselves. You could use an intermediate data transfer format like JSON or XML to pass data between the ... Read More

There are some cases where you can simply avoid using dictionaries in python. For example, if you're creating a dict of continuous integers to some values, consider using a list instead.If you're creating string-based keys, you might be better off using a Trie data structure(http://en.m.wikipedia.org/wiki/Trie).There are other cases where you ...
