Official abbreviation for: import scipy as sp/sc

Question

I've seen both:

import scipy as sp 

and:

import scipy as sc 

Is there an official preference listed anywhere?

For example, in the Introduction of the Scipy documentation, it is recommended to

import numpy as np import matplotlib as mpl import matplotlib.pyplot as plt 

but a similar abbreviation is not offered for the Scipy package.

In this question, sp is recommended, but the link to the Scipy docs doesn't actually specify sp over sc.

Answer 1

The "official" answer, according to the Scipy documentation, is that there is really no reason to ever

import scipy 

since all of the interesting functions in Scipy are actually located in the submodules, which are not automatically imported. Therefore, the recommended method is to use

from scipy import fftpack from scipy import integrate 

then, functions can be called with

fftpack.fft() 

Personally, I always use

import scipy.fftpack 

and live with the slightly longer function call

scipy.fftpack.fft(data) 

This way I know where the functions are coming from.
