How will you find the nearest value in a given numpy array?

We can use the argmin() method of numpy as shown below:

 

import numpy as np

def find_nearest_value(arr, value):

arr = np.asarray(arr)

idx = (np.abs(arr - value)).argmin()

return arr[idx]

#Driver code

arr = np.array([ 0.21169, 0.61391, 0.6341, 0.0131, 0.16541, 0.5645, 0.5742])

value = 0.52

print(find_nearest_value(arr, value)) # Prints 0.5645
