Why learn uv instead of the older python -m venv + pip steps?

• Speed. It installs packages dramatically faster — a real difference on slow connections.
• One tool. It manages Python versions, environments, and packages together, instead of three separate tools.
• Reproducible. It records exact versions in a lock file, so your project works the same on someone else's machine.
• Less to remember. Fewer commands, fewer mistakes.

The older venv + pip approach still works and is worth understanding (you saw it in the Virtual environments lesson). But for new projects, uv is the smoother path — especially when bandwidth is precious.
