Django and Flask are the two common Python web frameworks, and they take opposite approaches. Django includes an admin panel, user accounts, and database tools out of the box. Flask includes almost nothing, and you add libraries as needed. Neither is better in general. The right choice depends on what you are building and how much structure you want provided.
Deciding between them
- Pick Django when the project needs accounts, an admin area, and database models quickly, since all three are included.
- Pick Flask when building a small service or API, where Django's built-in pieces would sit unused.
- Consider what you want to learn: Django teaches conventions, while Flask teaches how the pieces fit together.
- Ignore popularity arguments. Both are widely used, and either teaches transferable web skills.
Build one complete project in your chosen framework before learning the other. Half a project in each teaches less than one finished project in either.
