In Python, you can use a generator to generate long pieces of text that do not contain useful information. A generator is a special kind of iterator that can generate data on demand, rather than generating all data at once. This saves memory, which is especially suitable for processing large amounts of data. The following is a sample code that shows how to use the generator to generate a long piece of text： ```python import random import string def generate_random_text(length): characters = string. ascii_letters + string. digits + string. punctuation for _ in range(length): yield random. choice(characters) # Generate 1000-character long text text = ''. join(generate_random_text(1000)) print(text) ``` In this example, the `generate_random_text' function is a generator function. It uses the `yield' keyword to generate random characters one by one, rather than generating all characters at once. Then, we use the'join` method to concatenate the generated characters into a string. You can adjust the length of the generated text as needed. For example, change the parameter `1000` in `generate_random_text(1000)' to another number to generate text of different lengths. The text generated by this method is composed of random letters, numbers, and punctuation marks, and does not contain any meaningful information. If you need specific types of characters or other rules, you can modify the `characters` variable according to your needs.
