What are some examples of ufuncs in Python?

Ufuncs, or universal functions, are functions that operate on ndarrays in an element-wise fashion. Examples include numpy.add, numpy.multiply, and numpy.sin.

Can you show me how to use numpy.add with arrays?

Sure! You can use numpy.add to add two arrays element-wise. For example:

import numpy as np
array1 = np.array([1, 2, 3])
array2 = np.array([4, 5, 6])
result = np.add(array1, array2)
print(result)  # Output: [5 7 9]

What about using ufuncs with conditions?

You can use ufuncs with conditions by combining them with numpy.where. For example:

result = np.where(array1 > 2, array1, 0)
print(result)  # Output: [0 0 3]
