Decode IASI Satellite Spectrum - convert IDL to python

Question

Since I have no experience in IDL coding, I need help converting the piece of code below to python.

The following parameters are known and are 1D arrays oder scalars.

IDefScaleSondNbScale, IDefScaleSondScaleFactor,
IDefScaleSondNsfirst, IDefScaleSondNslast,
IDefNsfirst

Answer 1

It's IDL and the python equivalent is the following:

SpectDecoded = np.empty_like(Spect, dtype=float)
for numScale in range(1, int(IDefScaleSondNbScale) + 1):
    SF = IDefScaleSondScaleFactor[numScale - 1]
    for chanNb in range(int(IDefScaleSondNsfirst[numScale - 1]), int(IDefScaleSondNslast[numScale - 1]) + 1):
        w = int(chanNb - IDefNsfirst[0])
        if w < SpectDecoded.shape[0]:
            SpectDecoded[w] = Spect[w] * 10 ** (-SF)
