Shuffle two list at once with same order

Question

I\'m using the nltk library\'s movie_reviews corpus which contains a large number of documents. My task is get predictive performance of these reviews

Answer 1

I get a easy way to do this

import numpy as np
a = np.array([0,1,2,3,4])
b = np.array([5,6,7,8,9])

indices = np.arange(a.shape[0])
np.random.shuffle(indices)

a = a[indices]
b = b[indices]
# a, array([3, 4, 1, 2, 0])
# b, array([8, 9, 6, 7, 5])
