Hi kcmileiq!

I think the confusion comes from what the range() function is doing, versus what the slicing is doing.

*(We can disregard the stride for now; it defaults to 1 if not named)*.

**To make it simpler, let's do:**

```
my_numbers = range(1, 5)
print my_numbers
```

We'll get a result of **[1, 2, 3, 4]** for **my_numbers**. Of course **5** is left out because the range includes the first number, but it excludes the last number.

Slicing works the same way (includes first, excludes last) but the important point is that **it refers to indexes, not the numbers themselves**.

So below:

```
my_numbers = range(1, 5)
x = my_numbers[1:3]
print x
```

Print x doesn't print **[1, 2]**, but rather **[2, 3]**, because **2** is actually at index number **1** and **3** is at index number **2** (**remember indexes start at 0**).

It's less confusing if we use letters:

```
letters = ["a", "b", "c", "d"]
mid = letters[1:3]
print mid
```

Print mid gives us ["b","c"], because "a" is at index 0, "b" is at index 1, "c" is at index 2, and "d" is at index 3.

I hope that makes sense!
