How to print array elements within a given range using Numpy?
In this program, we have to print elements of a numpy array in a given range. The different numpy functions used are numpy.where() and numpy.logical_and().
Algorithm
Step 1: Define a numpy array. Step 2: Use np.where() and np.logical_and() to find the numbers within the given range. Step 3: Print the result.
Example Code
import numpy as np
arr = np.array([1,3,5,7,10,2,4,6,8,10,36])
print("Original Array:\n",arr)
result = np.where(np.logical_and(arr>=4, arr<=20))
print(result)Output
Original Array: [ 1 3 5 7 10 2 4 6 8 10 36] (array([2, 3, 4, 6, 7, 8, 9], dtype=int64),)
Explanation
The result gives the index positions of elements which satisfy the condition in the np.where() function.
