Task
📝 **🏆 FINAL MISSION:** TODO list
📋 **Steps:**
1. Create empty `todos = []`
2. Append `{"task": "learn Python", "done": False}`
3. Append `{"task": "build TODO app", "done": True}`
4. Count completed: `sum(1 for t in todos if t["done"])`
5. Print the count
💡 **Similar example (books):**
```python
books = []
books.append({"title": "Python", "read": True})
books.append({"title": "Go", "read": False})
read_count = sum(1 for b in books if b["read"])
print(read_count) # 1
```
🎯 **Expected output:** `1`
