comment Solving multiple argument equations, choosing the dependent variable. [Python, Scipy]
Are you looking for an analytical or numerical solution? In the latter case, you can use scipy solvers with a lambda to forward/reorder arguments as needed.

comment random.sample in Python 3 (jupyter notebook)
There is no reason to do import scipy as sp even. Do from scipy import subpackage or from scipy.subpackage import something`.

comment How to get the spline basis used by scipy.interpolate.splev
(+1) This is likely the way to go, at least as long as github.com/scipy/scipy/pull/3174 is not merged.

comment How to get the spline basis used by scipy.interpolate.splev
What exactly do you mean by "per sample basis used splev when evaluating a spline"? You figured how to give splev knots and coefficients, what exactly are you looking for?

comment Multiple integrations of a data-function over a small portion of its domain - accuracy and efficiency
(+1) Style nitpick: you almost never want import scipy as sp. Better import interp, linspace et al from numpy directly.

comment Fortran version of python loop giving incorrect answer
However nice is Fortran for this sort of thing, at this level of complexity you're really better off just writing the code in cython using typed memoryviews.

comment pandas interpolation : use np.interp with changing values
Now that you're changing the question, I lose interest in cooking up a detailed reply, but basically: write yourself a solution using a for loop over the rows of your dataframe, then drop it to cython and you're all set.

if you only need linear interpolation, numpy.interp might be saner.

comment Preventing scipy eigenvectors differing from computer to computer
All caps are not helpful, you know :-). What I'm asking is whether you checked that you're not getting different linear combinations of eigenvectors for degenerate eigenvalues.
