user15567: Does anyone know of a good coin selection algorithm in Python that's perhaps similar to the one in Bitcoin Core (currently this: github/bitcoin/src/wallet.cpp (per guidance from stackexchange/1077))?
I see the popular python libraries: pybitcointools and pycoin both seem to be selecting all existing UTXOs which might not be optimal, and might fail @over 100 utxos. Andreas Antonopoulos' "greedy selection algo" is not as efficient as that in wallet.cpp of Bitcoin Core, am I right?

user5406: I'm currently compiling a master thesis on the topic of coin selection and I'm not aware of a Python implementation of Bitcoin Core's coin selection algorithm.
