Is there a special in scipy? ??

Overview

I want to find $ _4C_2 $ in python. It seems easy to do with scipy.special.comb, a library called scipy.

error

If you write as follows

import scipy
print(scipy.special.comb(4, 2))

error

AttributeError: module 'scipy' has no attribute 'special'

solution

It is OK to write as follows

from scipy.special import comb
print(comb(4, 2))

Execution result

6.0

The following is also possible

from scipy import special
print(special.comb(4, 2))

Summary

import scipy not from scipy.special import comb or from scipy import special
