■Explanation of the digitize function

Returns the position of a number in the specified array (this is called bin).

■Concrete example

import numpy as np

a=np.random.uniform(0,100,5) # Create an array with 5 numbers from 0 to 100
print(a)

　⇒ array([18.20175387, 68.02698607, 43.08681255, 45.76519616, 11.87886015])

b=np.digitize(a, bins=[15, 30, 45, 50, 60])
print(b)

　⇒ array([1, 5, 2, 3, 0], dtype=int64)

The result is as follows, which returns the position of a in the array defined by bin.
