python: find the index of a given value in a list ["foo","bar","baz"].index("bar")
Suppose that we are given a 2D numpy array and we need to find the row index of several values in this array. For example, if we are given an array as: [[1, 2], [3, 4], [5, 6], [7, 8], [9, 10]] And, we need to extract the indices of [1,2], [5,6] and [9...
