What libraries should I consider while making site in python?
user
For building a website with Python, there are several libraries and frameworks you may want to consider:

Django - A high-level, full-featured web framework that makes it easy to build robust, dynamic websites. It includes features like an ORM (Object-Relational Mapping), a template engine, and a URL dispatcher.

Flask - This is a micro-web framework that provides the core functionality required to build a website, while leaving the more complex aspects to third-party libraries. It's lightweight, flexible, and easy to learn, making it a popular choice for small to medium-sized projects.

Pyramid - A web framework that can be used for a wide range of applications, from small to large-scale projects. It provides a flexible and extensible architecture, making it a great choice for complex projects with specific requirements.

You would also want to consider using libraries for specific tasks, such as authentication (e.g. Flask-Login), templating (e.g. Jinja2), and database connectivity (e.g. SQLAlchemy). 

Ultimately, you'll likely end up choosing Flask for a quick start for smaller projects and Django for more complex projects.

What might I miss out on by choosing Django or Flask compared to the other one? Will it matter if my site gets very popular?

Flask:

Flask is a micro-framework, meaning it has a smaller set of built-in features, which can make it easier to learn and use for simple projects.
Flask is more flexible, allowing developers to choose their own libraries and components to build the website.
Flask is a good choice for projects that require custom functionality, as it is more lightweight and can be more easily customized.
Flask might require more setup and manual work to get the same level of functionality that Django provides out-of-the-box.
Django:

Django is a high-level framework that provides a lot of built-in functionality and features, making it easier to develop complex web applications quickly.
Django includes an ORM (Object-Relational Mapping) to interact with databases, a template engine, and a URL dispatcher, among other features.
Django provides a more structured way of building a web application, making it easier to maintain and scale.
Django can have a steeper learning curve due to its more comprehensive feature set and greater complexity.
In terms of handling high traffic, both Flask and Django can handle high traffic websites. However, Flask might require more manual optimization and scaling techniques, whereas Django provides more built-in scalability features, such as caching, middleware, and database sharding.

Ultimately, the choice between Django and Flask depends on your specific needs and the requirements of your project.  If you're building a simple website or prototype, Flask might be a good choice due to its simplicity and ease of use. If you're building a complex web application with many features and requirements, Django might be a better choice, given its comprehensive set of features and scalability.

In either case, it's important to consider your own skills, as well as the skills of any other developers you may be working with, when choosing a framework. If you're more familiar with one framework over the other, it may be more efficient and enjoyable to work with the one you already know, even if it might not be the best choice for your project in terms of features and functionality.
