Question
Given a 1D array, negate all elements which are between 3 and 8 (both inclusive)?Note: Generate the following arrayarray([1, 2, 3, 4, 5, 6, 7, 8, 9, 10])Print the Numpy array.
Solution
Here is a step-by-step solution using Python and Numpy:
Step 1: Import the numpy library
import numpy as np
Step 2: Create the 1D array
arr = np.array([1, 2, 3, 4, 5, 6, 7, 8, 9, 10])
Step 3: Negate the elements between 3 and 8
arr[(arr >= 3) & (arr <= 8)] *= -1
Step 4: Print the array
print(arr)
When you run this code, it will print:
array([ 1, 2, -3, -4, -5, -6, -7, -8, 9, 10])
This means that all elements between 3 and 8 in the array have been negated.
