How do I find the minimum and maximum values in a NumPy array?

You can use the numpy.min() and numpy.max() functions to find the minimum and maximum values in a NumPy array.

Can you show me an example of how to use these functions?

Sure! Here's a simple example:

import numpy as np

arr = np.array([1, 2, 3, 4, 5])
min_value = np.min(arr)
max_value = np.max(arr)
print('Min:', min_value)
print('Max:', max_value)

What if I have a 2D array?

For a 2D array, you can still use numpy.min() and numpy.max(), but you can specify the axis. For example:

arr_2d = np.array([[1, 2, 3], [4, 5, 6]])
min_value = np.min(arr_2d, axis=0)  # Min for each column
max_value = np.max(arr_2d, axis=1)  # Max for each row
