Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

1. 01

   Steep learning curve for non-Emacs users

   Elpy integrates deeply with Emacs, requiring familiarity with Emacs keybindings and configuration.

2. 02

   Limited documentation and community support

   Documentation is sparse in some areas, and the community size for Elpy is relatively small compared to other popular Python IDEs.

3. 03

   Performance issues with large codebases

   Elpy can become slow when working with very large Python projects due to its reliance on Emacs, which may not be optimized for such workloads.

4. 04

   Complex setup and configuration

   Users need to configure multiple components including Emacs, Elpy, and other dependencies manually.

What it does well

• Code completion and navigation

• Interactive Python shell integration
