AttributeError: module 'numpy' has no attribute 'long'

Question

I am trying to find 9 raise to power 19 using numpy.

I am using numpy 1.24.3

This is the code I am trying:

import numpy as np
np.long(9**19)

This is the error I am getting:

AttributeError: module 'numpy' has no attribute 'long'

Answer 1

Sadly, numpy.long was deprecated in numpy 1.20 and it is removed in numpy 1.24

If you wan the result you have to try numpy.longlong

import numpy as np
np.longlong(9**19)

#output
1350851717672992089
