A neural network is a machine learning model that uses a layered structure of interconnected nodes (aka neurons) to mimic the human brain's function and structure. Neural networks are a type of deep learning process called artificial intelligence (AI). 

Deep neural networks (DNN) are highly complex models that can have billions of parameters that are trained to perform some function.  LLMs (Large Language Models) such as ChatGPT are DNNs and what we today call AI. You should use these new AI tools to help write and debug your Python code.
