In large-scale Python applications and CLI tools, the overhead of importing numerous modules can lead to frustratingly slow startup times. PEP 810 proposes a formal mechanism for Lazy Imports, allowing the Python interpreter to defer the actual loading of a module until the moment it is first accessed.

This talk provides a deep dive into the mechanics of PEP 810. We will explore:

• The current challenges of the Python import system.
• How the proposed lazy keyword and transparent deferred loading work under the hood.
• The performance implications for application startup and memory usage.
• Potential “gotchas,” such as delayed ImportError exceptions and side effects.

Whether you are a library maintainer or a performance-focused developer, this session will help you understand how this proposed change could reshape the way we manage dependencies in Python.
