Write a program to get the positions where elements of a and b match. Hint:Use where function: Sample data : a = [1.2.3.2.3.4.3.4.5.61 b= [7,2,10,2,7,4,9,4,9,81 Sample output : [1 3 5 7]

Here is a Python program to get the positions where elements of a and b match:

import numpy as np

a = np.array([1,2,3,2,3,4,3,4,5,6])
b = np.array([7,2,10,2,7,4,9,4,9,8])

match_indices = np.where(a == b)[0]

print(match_indices)

Output:

[1 3 5 7]

Explanation:

1. We first import the numpy library.
2. We define the arrays `a` and `b` using the `numpy.array` function.
3. We use the `numpy.where` function to get the indices where the elements of `a` and `b` match. The output of `where` is a tuple containing an array of row indices and an array of column indices. Since we are dealing with 1-D arrays, we only need the row indices (which are at index 0 of the tuple). We access this array using the `[0]` index.
4. We print the resulting match_indices array.
