What are some examples of using structured arrays in NumPy?

Can you give me some examples of using structured arrays in NumPy?

Sure! Structured arrays in NumPy allow you to create arrays with complex data types. For example, you can define an array with fields like 'name', 'age', and 'height'.

How do I create a structured array with those fields?

You can create a structured array using the numpy.array function and specifying the dtype. Here's an example:

import numpy as np

# Define the data type
dtype = [('name', 'U10'), ('age', 'i4'), ('height', 'f4')]

# Create the structured array
data = np.array([('Alice', 25, 5.5), ('Bob', 30, 6.0)], dtype=dtype)

What can I do with the structured array once it's created?

You can access fields using their names, filter data, and perform operations. For example, to get all names:

names = data['name']
