Determine the shuffled indices of two lists/arrays

Question

As a challenge, I\'ve given myself this problem:

Given 2 lists, A, and B, where B is a shuffled version of A, the idea is to figure out the shuffled indices.

Answer 1

LOL

pd.Series(A).reset_index().set_index(0).ix[B].T.values[0]
#array([2, 3, 0, 1])
