Web18 mrt. 2024 · Not only does np.random.permutation help in shuffling arrays in ways that np.random.shuffle cannot, But it can also achieve the same results that shuffle produces on lists and arrays. In this section, we will learn the various similarities and differences between the two methods. Webmethod random.RandomState.permutation(x) # Randomly permute a sequence, or return a permuted range. If x is a multi-dimensional array, it is only shuffled along its first index. Note New code should use the permutation method of a Generator instance instead; …
