How do you find the maximum value in a NumPy array?

You can find the maximum value in a NumPy array by using the max() function. This function returns the largest value present in the array.

import numpy as np

# Creating a NumPy array
arr = np.array([1, 3, 5, 7, 9])

# Finding the maximum value
max_value = np.max(arr)
print(max_value)  # Output: 9

In this example, the max() function finds and returns the maximum value in the array arr, which is 9.

Finding the maximum value is a common operation in data analysis, statistics, and optimization tasks, where identifying the largest element in a dataset is often necessary.
