**Hint:** for item in collection:

### 7. What does the "len()" function do?

- Calculates the sum of all values
- Returns the total count of items

**Hint:** Short for "Length".

### 8. How do you check if "a" is equal to "b"?

- `a = b`
- `a == b`
- `a === b`
- `a.equals(b)`

**Hint:** Comparison requires two symbols.

- `typeof(x)`
- `check_type(x)`

**Hint:** type()

### 17. Which keyword brings in code from another module?

- `include`
