What is the difference between a package and a library?

Question

Accepted Answer

**Package** is a collection of modules. **Library** is a collection of packages for solving specific tasks.

**Package:**
- Single directory with `__init__.py`.
- Example: `requests`, `numpy`.

**Library:**
- Set of packages and modules.
- Example: Django (ORM, templates, auth, admin), Flask (minimal, but with extensions).

**Framework vs Library:**
- **Library** — you call it (you control flow).
- **Framework** — it calls you (inversion of control).

```python
# Library — you call functions
import requests
response = requests.get("https://api.example.com")

# Framework — it calls your code
# Django
def my_view(request):
    return HttpResponse("Hello")
```
