select max when comparing single element & array in python

Question

How to select max when comparing single element & array in python?

ex: i = 5 & a = np.array([3,9,1,4,6])

expected result is an array = [5,9,5,5,6]

by comparing i to each element of a & select the max.

Besides use for loop, is there a vectorization faster way?

maximum returns the max value of an elemet-wise comparison: np.maximum(a,i) — Brenlla

What you are looking for is numpy.maximum:

import numpy as np

i = 5
a = np.array([3,9,1,4,6])

print(np.maximum(i,a))
# [5,9,5,5,6]
