In this example, we have defined the string. In addition, we can treat strings as Python objects and store them in the Numpy array, since every Python object can be stored in the Numpy array using the object type. In contrast, we need to decode the bytes into human-readable characters for representation. Here, you can see that by using the str() method, we simply convert a unicode text into a plain string.
