# error in interface

this interface is buggie

slices.py
```favorite_things = ['raindrops on roses', 'whiskers on kittens', 'bright copper kettles',
'warm woolen mittens', 'bright paper packages tied up with string',
'cream colored ponies', 'crisp apple strudels']
slice1=favorite_things[1:4]
slice2=favorite_things[5:]
sorted_things=favorite_things
sorted_things.sort()
```

Hey Audie,

In your code, you are actually renaming `favorite_things` to `sorted_things`, not making a copy. In order to make a copy using slices, add [:] to the end of `favorite_things` (like this: `favorite_things[:]`) when you define sorted_things. Hope this helps!

EDIT: To correct what I said, after playing around with it a bit, you're assigning a new variable that points to the same location in memory, so you're not actually making a copy. Hopefully that clarifies the difference a little better!

I ran this code to test this:

```listy=[1, 2, 3, 4]
listy1 = listy
listies = listy[:]
print(listy1 is listy)
>>> True
print(listy is listies)
>>> False
```
