Day 13: Expecting range() to Return a List

Many beginners assume range() gives a list. It doesn’t.

---

❌ The Mistake

numbers = range(5)
print(numbers[0])

---

✅ The Correct Way

numbers = list(range(5))
print(numbers[0])

Convert it to a list if you actually need one.

---

❌ Why This Fails?

range() returns a range object, not a list.
It’s iterable but doesn’t store all values in memory.

---

✔ Key Points

• range() → returns a range object

• Use list(range()) when a real list is required

---

🧠 Simple Rule to Remember

• range() is memory-efficient

• It behaves like a sequence, not a list
