Re: [Quantlib-users] Quantlib installation on Ubuntu - bucketAnalysis function missing

[Luigi B. <lui...@gm...>]

Hello,
    not all C++ functionality is available from Python — it's a partly
manual process, so it's done when things are needed or requested.  You can
see what's exported by looking into <
https://github.com/lballabio/QuantLib-SWIG/tree/master/SWIG>.

You can open an issue on GitHub to request that function to be exported.
However, it might be easier to write something similar in Python.  The idea
is to calculate the initial NPV of the instruments, then bump the quotes
and calculate the NPV again.

Hope this helps,
    Luigi
